摘要： This disclosure is generally concerned with devices for determining photocurrent levels. One example of such a device is an optoelectronic device that includes a photodetector. The photodetector is configured to receive an optical signal and generate a corresponding electrical signal. The electrical signal is received by a pre-amplifier circuit which then converts the received electrical signal to a differential output. Finally, a post-amplifier circuit in communication with the first stage circuit is configured to derive an optical signal strength of the optical signal based upon the differential output received from the pre-amplifier circuit.

摘要： A preamplifier circuit, a clock switching circuit, and an optical receiver are provided that include a preamplifier that controls a bandwidth for conducting amplification on an input signal by varying a feedback resistance according to a control signal; a control signal generating part that determines the band of the output signal of the preamplifier to generate the control signal; and a correction signal generating part that generates a correction signal for correcting the control signal; wherein the correction signal corrects the control signal to adjust the feedback resistance. Accordingly, even when the number of rises and falls of an optical input signal in a given time period is less than a predetermined number range, the control signal may be properly generated to successfully conduct band control. Thus, an optical receiver that is not dedicated to a predetermined input signal pattern but is rather capable of automatically adjusting its bandwidth may be realized, and the cost of manufacturing the optical receiver structure may be reduced.

摘要： An optical receiving device. The optical receiving device has a photodiode, transimpedance amplifier, and a feedback component. The photodiode has a first terminal coupled to a voltage source and a second terminal. When detecting an optical signal, the photodiode generates a current signal output from the second terminal. The transimpedance amplifier converts the current signal to a voltage signal and outputs the voltage. The feedback component is coupled between the first terminal and a input terminal of the transimpedance amplifier. The feedback component feeds a first voltage-changing signal, occurring in the input terminal of the transimdepance amplifier with the current signal, to the first terminal.

摘要： A software enabled control method that allows dynamic configuration of the operation of a control system. The configuration can be done in a factory calibration or while the system is running in the field in communication with a Host computer. The Host computer may communicate through a serial or parallel I/O. Because the control system has an expert system with built-in mathematical models and intelligence for the system with luminent devices, once the software enabled control system has been configured and given set points for desired target performance, it will regulate performance of the system with a luminent device in a manner that does not require intervention of the Host computer. The system contains performance optimization monitors based on predetermined criteria. The results of the monitors are available to the user or a Host computer through one of the available I/Os. The present invention allows flexibility to address various luminent devices using the same software architecture and similar algorithms. The present invention has a control system that can be configured to address a specific luminent device allowing for compensation of manufacturing. The control system also has algorithms that can be dynamically changed in light of changing environmental conditions.

摘要： A method and apparatus for compensating, in the electrical domain, for chromatic dispersion of an optical signal is disclosed. An optical signal is converted to an electrical signal comprised of components which are recoverable and components which are not directly recoverable. A first approximation of the output is derived by applying a transfer function to the electrical signal. The components of the electrical signal which are not directly recoverable are then estimated by applying a second transfer function to the first approximation. After removing these components a second approximation of the output is obtained by re-applying the first transfer function to the result. The optical signal may have a suitably small extinction ratio to improve compensation. The square root of the electrical signal may be taken to improve compensation. A better approximation may be achieved by re-applying the above method iteratively.

摘要： An optical element for simultaneously retrieving the tributary data rate and the clock frequency from the line rate of an OTDM signal. The demultiplexing and clock recovery principle is based on injection locking of a high-Q-filtered and high gain loop with a variable phase delay and an EA-modulator with high non-linear response, i.e., absorption verses applied voltage. A modulator that is preferably an EA-modulator, an amplifier preferably an erbium doped fiber amplifier (“EDFA”), a base band receiver, an electronic amplifier, a high-Q filter, and a variable phase delay are arranged in a loop to provide an oscillator for simultaneously retrieving tributary data rate and clock frequency.

摘要： An optical communication system, using a radio frequency (RF) signal for communicating an analog communication signal, includes an optical transmitter and an optical receiver. The optical transmitter generates a reference light beam, generates a phase modulated communication light beam by phase modulating the reference light beam with the analog communication signal, polarizes a portion of the reference light beam and combines the polarized reference light beam and the phase modulated communication light beam. The optical receiver separates the reference light beam and the communication light beam, develops a shifted light beam that is shifted in frequency by the RF frequency, interferometrically combines the communication light beam with the shifted light beam to provide a heterodyne signal including information regarding the state of phase of the communication light beam, uses the heterodyne signal to produce an electrical signal at an optical beat frequency corresponding to the RF and with a phase corresponding to the state of phase of the communication light beam, and derives from the RF signal and the heterodyne signal an output signal that has a linear correspondence to the state of optical phase of the communication light beam and the analog communication signal.
