摘要： Consistent with the present disclosure, one or more spare Widely Tunable Lasers (WTLs) are integrated on a PIC. In the event that a channel, including, for example, a laser, a modulator and a semiconductor optical amplifier in a transmitter or Tx PIC, or a laser, optical hybrid, and photodiodes, for example, in a receiver PIC (Rx PIC), includes one or more defective devices, a spare channel is selected that includes a widely tunable laser (WTL) which may be tuned to the wavelength associated with any of the channels on the PIC. Accordingly, the spare channel replaces the defective channel or the lowest performing channel and outputs modulated optical signals at the wavelength associated with the defective channel. Thus, even though a defective channel may be present, a die consistent with the present disclosure may still output or receive the desired channels because the spare channel replaces the defective channel. As a result, yields and minimum performance may improve compared to PICs that do not have a spare channel and manufacturing costs may be reduced. Alternatively, connections, such as fiber connections, may be made only to the operation or best performing channels.

摘要： Consistent with the present disclosure, active devices, such as lasers, optical amplifiers, and photodiodes, are integrated on a first substrate, and other optical devices, such as passive devices including polarization rotators and polarization beam combiners, are provided on a second substrate. An array of lenses is provided between the two substrates to provide a low loss optical connection from the first substrate to the second substrate. In addition, the orientation or position of the lenses can be readily controlled with Microelectromechnical System (MEMS) actuators so that the light can be directed precisely to a desired optical element, such as a waveguide. Consistent with a further aspect of the present disclosure, the lenses may be controlled to be misaligned by varying degrees in order to control the amount of light that is supplied from one substrate to another. Accordingly, the lenses may act as variable optical attenuators to provide uniform optical power levels, for example, or any desired power distribution.

摘要： An uncooled, through-hole configured laser module adapted to receive and transmit RF signals to a laser at bandwidths from direct current (DC) to about ten gigahertz. The laser module incorporates an option for two pin-out configurations. One pin-out configuration has one ground pin and one signal pin for operation at about one gigabit/second or one gigahertz. The second high performance pin-out uses two ground pins and one signal pin for operation up to about ten gigabit/second or ten gigahertz.

摘要： An optical transceiver assembly for use in a bidirectional system includes a beam splitter to direct an incoming signal to a photodiode. An outgoing signal from a laser diode is partially transmitted and partially reflected by the splitter. The reflected signal, which may reach the photodiode, constitutes crosstalk which is reduced by orienting the polarization direction of the splitter essentially parallel to that of the outgoing signal from the laser diode. In another embodiment, which enhances coupling efficiency, a single element asphere lens is positioned between the laser diode and the splitter.

摘要： Consistent with the present disclosure, an apparatus for producing a control signal for a laser source is provided, comprising an etalon configured to receive light from the laser source and control circuitry that provides the control signal, wherein the control signal is indicative of a comparison of (a) a difference between a forward transmission signal of the etalon and a backward reflection signal of the etalon and (b) the light received by the etalon from the laser source. Alternatively, the control signal is indicative of a comparison of (a) a difference between a forward transmission signal of the etalon and a backward reflection signal of the etalon and (b) a combination of the forward transmission signal of the etalon and the backward reflection signal of the etalon. Also consistent with the present disclosure, a method of aligning an etalon-based wavelength locking apparatus is provided, wherein the etalon of the apparatus is aligned with an optical axis along a direction of propagation of the output of the laser source by monitoring the signals indicative of the forward transmission signal and the backward reflection signal of the etalon.

摘要： Consistent with one example of the disclosed implementations, a photonic integrated circuit (PIC) may be provided that includes s group of lasers and an arrayed waveguide grating (AWG) disposed on a substrate. Each laser in the group may supply an optical signal, such that each optical signal has a different wavelength. Each laser may be tunable to at least two designated wavelengths, which are separated from one another by a free spectral range (FSR) of the AWG. As a result, the optical signals provided from each laser may be combined by the AWG, regardless of which designated wavelength the optical signals have. Accordingly, a PIC may be provided that has a relatively simple construction but can supply optical signals having tunable wavelengths.

摘要： Pairs of distributed feedback (DFB) lasers are provided on a substrate. An arrayed waveguide grating (AWG) is also provided on the substrate having input waveguides, each of which being connected to a corresponding pair of DFB lasers. The wavelengths of optical signals supplied from each pair of DFB lasers may be spectrally spaced from one another by a free spectral range (FSR) of the AWG. By selecting either a first or second DFB laser in a pair and temperature tuning to adjust the wavelength, each pair of DFB lasers can supply optical signals at one of four wavelengths, pairs of which are spectrally spaced from one another by the FSR of the AWG. A widely tunable transmitter may thus be obtained.
