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： A multi-port fiber optic device (100) includes a pair of opposite collimators (50, 51), of which each includes a V-groove dual fiber ferrule (20, 21) with a GRIN rod lens (2, 1). At least one band-pass DWDM thin film filter (4) is securely sandwiched between the two opposite GRIN rod lens (2, 1) of the pair of collimators (20, 21). The V-groove dual fiber ferrule (20, 21) is used to couple light in and out thereof and tune the thin film filter center wavelength to the ITU grid. The light coupled in from the input fiber (13) of the V-groove dual fiber ferrule (20) will be collimated and transmitted to the DWDM thin film filter (4). The part of the in-pass-band light will pass through the filter (4) as performing a demultiplexed channel and is successively coupled into the other collimator (21) aside.

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： Improved designs of optical multiplexing/demultiplexing module are disclosed for use in multiplexing a composite optical signal into respective individual channels or wavelengths or demultiplexing individual channels or wavelengths into a composite optical signal. According to one embodiment, the optical multiplexing/demultiplexing module comprises an array of collimators, an array of optical filters and an array of mirrors. The collimators are boned to a common substrate after being aligned with a respect optical filter. Different from the prior art devices, the aligned positions of the collimators are secured or held up by preformed wedges. A bonding agent is then applied only to respective contacts between the collimators and the wedges. The wedges are further bonded to a common substrate to secure the collimators.

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.
