摘要： An optoelectronic circuit includes a resonant cavity formed on a substrate and into which is injected an input digital optical signal that encodes bits of information (each bit representing an OFF logic level or an ON logic level). A heterojunction thyristor device, formed in the resonant cavity, produces an output digital electrical signal corresponding to the input digital optical signal. A sampling clock defines sampling periods that overlap the bits (e.g., ON/OFF pulse durations) in the input digital optical signal. The sampling clock can be in the form of electrical pulses supplied to the n-channel injector terminal(s) and/or p-channel injector terminals of the heterojunction thyristor device. Alternatively, the sampling clock can be in the form of optical pulses that are part of the Optical IN signal that is resonantly absorbed by the device. The heterojunction thyristor device operates in an OFF state and an ON state. In the OFF state, current does not flow between an anode terminal and a cathode terminal of the device; while in the ON state, current flows between the anode terminal and the cathode terminal. To provide optical-to-electrical conversion of the digital bit stream, the heterojunction thyristor device switches from its OFF state to its ON state in the event that, during a given sampling period, the light intensity level of the input digital optical signal corresponds to the ON logic level; however, it does not switch into the ON state (and remains in the OFF state) in the event that, during the given sampling period, the light intensity level of the digital optical signal corresponds to the OFF logic level.

摘要： A serial photonic digital-to-analog converter employs a heterojunction thyristor device configured for optically-controlled sampling/switching to convert a digital word encoded by a serial digital optical data signal (e.g., serial optical bit stream) into a corresponding analog electrical signal. A voltage reference is operably coupled to the electrical input terminal of the heterojunction thyristor device. The voltage reference cooperates with the heterojunction thyristor device to sequentially generate at its electrical output terminal a voltage signal representing contribution of each bit of the digital word encoded in the serial digital optical data signal. A summing network is operably coupled to the electrical output terminal of the device. The summing network sequentially sums contribution of the voltage signal over the sequence of bits to produce an analog electrical signal corresponding to the digital word for output therefrom. Preferably, the summing network includes an adding node, sample and hold circuit, and a feedback path between the sample and hold circuit and the adding node. In addition, the voltage reference preferably supplies a voltage level corresponding to the maximum voltage level of the analog electrical signal divided by 2(N−1), where N is the number of bits in said digital word, and the feedback path comprises an amplifier that amplifies output of the sample and hold circuit by a factor of 2.

摘要： An integrated circuit includes a heterojunction thyristor device having an anode terminal, a cathode terminal, a first injector terminal operably coupled to a first quantum well channel disposed between the anode terminal and the cathode terminal, and a second injector terminal operably coupled to a second quantum well channel disposed between the anode terminal and the cathode terminal. Bias elements operate the heterojunction thyristor device in a mode that provides substantially linear voltage gain for electrical signals supplied to at least one of the first and second injector terminals for output to at least one output node. Preferably, the bias elements include a first DC current source operably coupled to an n-type modulation doped quantum well structure, a second DC current source operably coupled to a p-type modulation doped quantum well structure, a first bias resistance operably coupled between a high voltage supply and the anode terminal, and a second bias resistance operably coupled between the cathode terminal and a low voltage supply. The bias elements provide a current passing from the anode terminal to the cathode terminal that is below a characteristic hold current for the heterojunction thyristor device to thereby inhibit switching of the heterojunction thyristor device. The DC current provided by the DC current sources controls the amount of voltage gain provided by the heterojunction thyristor device.

摘要： An optoelectronic integrated circuit includes a resonant cavity formed on a substrate. A heterojunction thyristor device is formed in the resonant cavity and operates to detect an input optical pulse (or input electrical pulse) and produce an output optical pulse via laser emission in response to the detected input pulse. The heterojunction thyristor device includes a channel region that is coupled to a current source that draws current from the channel region. Time delay between the input pulse and output optical pulse may be varied by configuring the current source to draw constant current from the channel region and modulating the intensity of the input pulse, or by varying the amount of current drawn from the channel region by the current source. The heterojunction thyristor device may be formed from a multilayer structure of group III-V materials, or from a multilayer structure of strained silicon materials. A plurality of such heterojunction thyristor based optoelectronic integrated circuits can be used to provide variable pulse delay over a plurality of channels. In addition, the heterojunction thyristor device is easily integrated with other optoelectronic devices formed from the same growth structure to form monolithic optoelectronic integrated circuits suitable for many diverse applications, including phased array communication systems.

摘要： An optoelectronic circuit employing a heterojunction thyristor device that is configured as an optically-controlled (or electrically-controlled) sampling/switching device. First and second channel regions are disposed between the anode terminal and the cathode terminal of the device, and an electrical input terminal and an electrical output terminal are coupled to opposite ends of the first channel region. At least one control signal is supplied to the device. When the control signal corresponds to a predetermined ON condition, sufficient charge is stored in the second channel region to cause the heterojunction thyristor device to operate in an ON state whereby current flows between the anode terminal and the cathode terminal and the electrical input terminal is electrically coupled to the electrical output terminal. When the control signal corresponds to a predetermined OFF condition, the heterojunction thyristor device operates in an OFF state whereby current does not flow between the anode terminal and the cathode terminal and the electrical input terminal is electrically isolated from the electrical output terminal. The control signal can be an optical sampling clock, a digital optical signal encoding bits of information, the combination of a digital optical signal and an optical sampling clock (which defines sampling periods that overlap the bits of information in the digital optical signal), or an electrical sampling clock.

摘要： A photonic digital-to-analog converter employing a plurality of heterojunction thyristor devices that are configured to convert a digital word encoded by a parallel digital optical signal (e.g., a plurality of synchronous optical bits) to an output analog electrical signal whose magnitude corresponds to the digital word. Each heterojunction thyristor device is configured to convert an optical bit in the digital word to a corresponding digital electrical signal. The voltage levels (e.g., magnitudes) of the ON state of the digital electrical signals produced by the heterojunction thyristor devices may be supplied by voltage divider networks coupled between the cathode terminal of the devices and ground potential or voltage reference sources coupled to the input terminals of the heterojunction thyristor devices. In this manner, electrical signals whose magnitude corresponds to contribution of each optical bit in the digital word are produced. These electrical signals are summed by a summing network to generate the output analog electrical signal corresponding to the digital word.
摘要翻译：一种采用多个异质结晶闸管器件的光子数模转换器，其被配置为将由并行数字光信号（例如，多个同步光位）编码的数字字转换为输出模拟电信号，其大小对应于数字词。每个异质结晶闸管器件被配置为将数字字中的光学位转换成相应的数字电信号。由异质结晶闸管器件产生的数字电信号的导通状态的电压电平（例如，大小）可由耦合在器件的阴极端子和耦合到输入端子的地电位或电压参考源之间的分压器网络提供的异质结晶闸管器件。以这种方式，产生其幅度对应于数字字中每个光学位的贡献的电信号。这些电信号由求和网络相加以产生对应于数字字的输出模拟电信号。
