    摘要: A monolithic vertical optical cavity device built up along a vertical direction. The device has a bottom Distributed Bragg Reflector (DBR), a Quantum Well (QW) region consisting of least one active layer grown on top of the bottom DBR by using a Selective Area Epitaxy (SAE) mask such that the active layer or layers exhibit a variation in at least one physical parameter in a horizontal plane perpendicular to the vertical direction and a top DBR deposited on top of the QW region. A spacer is deposited with or without SAE adjacent the QW region. The device has a variable Fabry-Perot distance defined along the vertical direction between the bottom DBR and the top DBR and a variable physical parameter of the active layer. The varying physical parameter of the active layers is either their surface curvature and/or the band gap and both of these parameters are regulated by SAE. The monolithic vertical cavity device can be used as a Vertical Cavity Surface Emitting Laser (VCSEL) or a Vertical Cavity Detector (VCDET).

    摘要: A circuit and method are provided herein for monitoring the status of a clock signal. In general, the method may include supplying a pair of clock signals to a clock monitor circuit, which is configured for monitoring a status of one clock signal relative to the other. The status indicates whether the frequency of the one clock signal is faster, slower or substantially equal to the frequency of the other clock signal. Once determined, the status may be stored as a bit pattern within a status register, which is operatively coupled to the clock monitor circuit. This enables the status to be read by detecting a logic state of one or more bits within the status register.

    摘要: A multiplexer for a wavelength division multiplexed optical communication system includes an optical circulator with at least first, second, third and fourth circulator ports. An optical fiber with a first optical transmission path is coupled to the first circulator port and carries a wavelength division multiplexed optical signal that includes signals 1−n. A second optical transmission path is in optical communication with the second circulator port. A first laser is coupled to the second optical transmission path. The first laser reflects the 1−n signals and adds a signal n+1. A control loop is coupled to the first laser. In response to a detected change in temperature the control loop sends a signal to adjust a voltage or current supplied to the first laser and provide a controlled frequency and power of an output beam. A third optical transmission path is in optical communication with the third circulator port and transmits the signals 1−n and the signals n+1 that are received from the optical circulator. A fourth optical transmission path is in optical communication with the fourth optical circulator port. The fourth optical transmission path is positioned after the second optical transmission path and before the third optical transmission path. A first optoelectronic device is coupled to the fourth optical transmission path.

    摘要: An electronic circuit suitable for sampling an incoming data bit stream in order to recover the information contained in the data stream contains an input section, a reference section, and a comparing section. The input section produces a ramp signal that switches between a first endpoint voltage and a second endpoint voltage in a periodic manner. The reference section furnishes a plurality of reference voltages between the two endpoint voltages. The comparing section compares the ramp signal to the reference voltages to produce corresponding sampling signals. Each sampling signal makes a first voltage transition as the ramp signal passes a corresponding reference voltage in going from the second endpoint voltage to the first endpoint voltage. Accordingly, the first transitions of the sampling signals occur in groups, each group being spread out in time during part of a period of the ramp signal. A data sampling portion of the circuit utilizes the sampling signals to sample the input data bit stream.
