    • Methods and apparatuses to provide wavelength locked WDM Passive Optical Networks (“PONs”) are described. A first transceiver transmits a set of optical signals in a first direction along a wavelength channel. A second transceiver transmits another set of optical signals along the same wavelength channel in another direction. The wavelength of the first transceiver is locked using an optical power of the optical signals of the second transceiver. The wavelength of the second transceiver is locked using the optical power of the optical signals of the first transceiver. A WDM MUX/De-MUX is coupled between the first transceiver and the second transceiver. An in-line gain element can be coupled to the WDM MUX/De-MUX to amplify the optical signals. The first transceiver and the second transceiver operate in a saturated gain condition.

    • Methods and apparatuses to provide an “Open access” service model using wavelength division multiplexing (“WDM”) passive optical networks (“PONs”) are described. A cross-connect is used to supply a first set of optical signals corresponding to a first service provider and a second set of optical signals corresponding to a second service provider to a WDM multiplexer/demultiplexer. The WDM multiplexer/de-multiplexer is used to multiplex and transmit the first set and the second set to a remote location. Another WDM multiplexer/de-multiplexer at the remote location is used to de-multiplex the first set and the second set. The first set may be supplied to a first user and the second set may be supplied to a second user. Transceivers coupled to the cross-connect may be used to generate the optical signals. For one embodiment, the transceivers include a wavelength-locked light source. For one embodiment, the transceivers are alike.

    • A tunable optical resonator whose resonance frequency is determined by a light signal introduced into the resonator. The resonator includes an optical cavity having a first mirror and a second mirror. The first mirror and second mirror are supported relative to one another such that the distance between the first and second mirrors may be altered by applying a force to said second mirror thereby altering the resonance frequency of said cavity. The resonator includes a light input port for receiving a tuning light signal, and a light signal generator for generating the tuning light source. The tuning light signal is introduced into the optical cavity such that the tuning light signal is reflected between the first and second mirrors. In the absence of the tuning light signal, the resonator has a resonance characterized by a resonance response curve centered at &lgr;0. The tuning light signal has a wavelength &lgr;1 within said resonance response curve and sufficient power to cause said resonance response curve to shift such that the resonance response curve is now centered at &lgr;2, where &lgr;2>&lgr;1. In one embodiment of the invention, a circuit for monitoring the light leaving the resonator is utilized to control the wavelength and/or amplitude of the tuning light signal such that the light leaving the resonator has a predetermined wavelength.

    • An optical heterodyne detection system includes an input signal and a local oscillator signal that are combined in an optical coupler and output as a first beam and a second beam. A polarizing beam splitter is optically connected to the optical coupler in order to receive the first beam and the second beam. The polarizing beam splitter includes four outputs for outputting four beams to four photodetectors including two polarized portions of the first beam and two polarized portions of the second beam. The four photodetectors generate four electrical signals in response to respective ones of the four beams. The four electrical signals are transmitted to a processor and processed to provide an output response that is independent of the polarization state of the original input signal and in which the intensity noise has been suppressed. Processing of the electrical signals to suppress the intensity noise involves canceling the intensity noise component of similarly polarized beams by subtracting the similarly polarized beams. Processing of the electrical signals to provide polarization independence involves squaring the values generated from the two subtraction operations, low pass filtering the values generated from the two squaring operations, and then adding the values generated from the two filtering operations.
    • 光外差检测系统包括输入信号和本地振荡器信号,其组合在光耦合器中并作为第一光束和第二光束输出。 偏振分束器光学连接到光耦合器以便接收第一光束和第二光束。 偏振分束器包括四个输出,用于将四个光束输出到四个光电检测器,包括第一光束的两个偏振部分和第二光束的两个偏振部分。 四个光电检测器响应于四个光束中的相应的四个光束产生四个电信号。 四个电信号被发送到处理器并被处理以提供独立于原始输入信号的偏振态的输出响应,并且其中已经抑制了强度噪声。 抑制强度噪声的电信号的处理涉及通过减去相似偏振光束来消除类似偏振光束的强度噪声分量。 电信号的处理以提供偏振独立性涉及平方从两个减法运算产生的值,对从两个平方运算产生的值进行低通滤波,然后将从两个滤波运算产生的值相加。
