摘要： Fiber optical interleavers based on a retro-reflective structure are disclosed. The retro-reflective structure includes three stages of optical components. A first stage includes walk-off crystals, at least one of the crystals is used to displace a received optical signal with multiplexed bands or channels therein into a first ray (e.g. an O-ray) and a second ray (e.g. an E-ray). A second stage following the first stage includes at least a pair of birefringent crystals to form an interferometer that create path or phase differences introduced by the birefringent index differences between the first ray and the second ray. A third stage following the second stage includes a pair of half wave plates, a walk-off crystal and a quarter wave plate, wherein the quarter wave plate has a highly reflective coating on one end to retro-reflect light beams back through the same stages. Respective reflected and processed first ray and second ray are then combined in the first stage to output respective demultiplexed beams.

摘要： An optical fiber structure for demultiplexing/multiplexing includes a coupler which splits an incoming signal with multiple channels into two substantially identical signals that are respectively processed to separate the closely located successive channel groups for further demultiplexing or multiplexing. The spectrum characteristics to process the two identical signals are so chosen that the channel distortion and/or transmission loss are minimized. In particular, multiple stages of splitter filters are used to shorten the transmission path a channel signal has to pass through. As a result, signal distortion and/or transmission loss are minimized and the channel groups are interleaved by a single channel group.

摘要： Optical devices and methods for regulating optical channel signals with specified wavelengths are disclosed. According to one aspect of the present invention, a number of variable optical apparatuses are employed. Each of the variable optical apparatuses includes a first and a second optical channel module, both configured at a wavelength λi. Each of the variable optical apparatuses further includes an optical regulator (i.e. a neutral density filter controlled by a stepper motor) coupled between the first and second optical channel modules. When signals with different wavelengths arrive, only the signal with the wavelength λi will transmit through the first optical channel module and the rest are reflected off. The transmitted signal is regulated (i.e. attenuated or strengthened) accordingly by the optical regulator before transmitting through the second optical channel module. Hence, the signals with different wavelengths can be respectively regulated by one of the variable optical apparatuses.

摘要： Techniques for calibrating tunable optical devices using a probing signal as a reference so as to achieve an accurate control over an absolute wavelength of the tunable optical devices. A probing signal being a calibrated optical signal with a spectrum centered at a desired add/drop channel or wavelength is introduced into an N-port circulator coupled between two tunable optical devices. When the two tunable optical devices are tuned not exactly at the desired wavelength, a portion of probing signal will be reflected or dropped out by the two tunable optical devices. The dropped probing signal is detected and coupled to a signal processor or circuitry configured to generate adjustments to or the control signals for controlling the tunable optical devices in accordance with the reflected probing signal being maximized.
