摘要： A compact WDM optical device can demultiplex an optical laser signal containing several different wavelengths corresponding to particular channels, and, in reverse operation operate as a multiplexer to interleave several different wavelengths into a multiplexed multi-channel optical laser signal with improved insertion loss characteristics. The optical device includes a linear array of passive resonant optical cavities, in the form of Fabry-Perot filters, extending in a lateral direction and an integral array of associated microlenses extending in the lateral direction. Each microlens has a center which is offset from the central longitudinal axis of an associated Fabry-Perot filter to reflect laser radiation through the device. Each optical cavity is tuned by adjusting the longitudinal dimension thereof to a particular wavelength contained in the multi-channel optical signal. A stepped-wavelength steered laser radiation source for the optical device uses a VCSEL array with offset microlenses. With an additional row of microlenses the optical device can be used for wavelength routing and channel dropping applications. A stepped-wavelength WDM VCSEL array can be similarly organized to form a WDM combiner or multiplexer.

摘要： A polarization independent tunable filter/receiver for optical communications. The tunable filter, operating as a directional coupler, has three waveguides including a central, feedguide (32) and a pair of branch waveguides (34, 36). Through either electro-optic effects or free carrier injection, the TM and TE polarization modes of the central wavelength can be coupled from the feedguide (32) to the appropriate branch guide. The separated modes can be either detected independently (40, 42) or reunited in phase for further processing.

摘要： An optical multiplexing device spatially disburses collimated light from a fiber optic waveguide into individual wavelength bands, or multiplexes such individual wavelength bands to a common fiber optic waveguide or other destination. The optical multiplexing device has application for dense channel wavelength division multiplexing (WDM) systems for fiber optic telecommunications, as well as compact optical instrument design. Multiple wavelength light travelling in a fiber optic waveguide is separated into multiple narrow spectral bands directed to individual fiber optic carriers or detectors. An optical block (10) has an optical port for passing the aforesaid multiple wavelength collimated light, and multiple ports arrayed in spaced ralation to each other along a multiport surface of the optical block. A continuous, variable thickness, multi-cavity interference filter (22) extends on the multiport surface of the optical block over the aforesaid multiple ports. At each of the multiple ports the continuous interference filter transmits a different wavelength sub-range of the multiple wavelength collimated light passed by the optical port, and reflects other wavelengths. Multicolor light passed to the optical block from the optical port is directed to a first one of the multiple ports on an opposite surface of the optical block. The wavelength sub-range which is "in-band" of such first one of the multiple ports (44...54) is transmitted through that port by the local portion of the continuous, variable thickness interference filter there, and all other wavelengths are reflected. The light not transmitted through the first port is reflected to strike a second port, at which a second (different) wavelength band is transmitted and all other light again reflected. The reflected optical signals (32) thus cascade in a "multiple-bounce" sequence down the optical block of the multiplexing device, sequentially removing each channel of the multiplexed signal. In reverse operation, individual channels are combined in the optical block and transmitted through the optical port.

摘要： A multi-wavelength optical filtering device for optical signal transmission, capable for functioning as a multiplexer or a demultiplexer. The device has at least one (first) optical circulator having at least four ports including an input port and a plurality of sequential ports, the last of said sequential ports being an output port, and an in-fiber Bragg grating (wavelength selective means) coupled to each of said sequential ports except said output port. The circulator may be branched off to a number of other circulators, the number depending on the number of the sequential ports of the first circulator, through the Bragg grating rather than through the output port of the first circulator. The other circulators, which are preferably also at least four-port circulators with wavelength selective means at the sequential ports, can also be branched off in an analogous manner as the first circulator. The device allows a reduction of signal losses in optical signal transmission due to the passing of a signal between circulator ports.

摘要： An integrated optical isolator arrangement is described that is capable of isolating an input optical signal and coupling a pump signal. The coupler includes a pair of lenses with an isolator disposed therebetween. The isolator is sandwiched between a splitter/filter and a wavelength selective device. An end face of each lens has an input and an output port for receiving and transmitting optical signals. The splitter/filter is selected to transmit some of the input signal on a first input port and to reflect the remaining untransmitted portion of the input optical signal to a first output port proximate to the first input port. The wavelength selective device allows the input signal from the first input port to pass through it to a second output port, and in addition, reflects a pump signal transmitted on the second input port to the second output port for combination with the input optical signal.

摘要： A wavelength-selective optical coupler has an optical coupler (C) arranged between two waveguide structures. The coupler (C) has a coupling zone arranged between said waveguide structures and a Bragg cell (B) within said coupling zone. In a preferred embodiment, the optical coupler (C) is a 100 % light-transmitting coupler. In various different embodiments, the coupler (C) is made of optical fibres or by techniques of optoelectronic integration on a semiconductor glass or silica substrate. The Bragg cell (B) has a constant, multiple or variable pitch. The invention has applications in optical wavelength multiplexing information transmission systems. Said coupler is to be made using standard diameter fibres. However, such fibres have a low Germanium (Ge) content giving them low sensitivity to UV light and making inscription of the Bragg pattern difficult. This problem can be solved by sensitising the fibre to UV light in a different manner, such as by increasing the hydrogen content within the fibre by placing the coupler in a hydrogen atmosphere at high pressure (100-300 bars) for a few weeks. An adequate quantity of hydrogen will be absorbed to make the fibres UV-sensitive and to enable Bragg pattern inscription in the coupling region.

摘要： A compact optical transceiver includes a ceramic mounting block (1), with a laser diode (3) abutting a first end of the mounting block for generating light of a first wavelength. A GRIN lens (5), mounted to the mounting block, then receives and focuses the generated light to an optical fiber (13) which is attached to the compact optical transceiver. A dichroic substance (7) acts as a beamsplitter by passing light of a first wavelength and deflecting light of a second wavelength. The dichroic substance (7) is coated on a glass plate, which is mounted in a first angular groove of the mounting block. The beamsplitter (7) receives and passes the generated light of the first wavelength which has been focused by the GRIN lens (5). From a remote transmitter, light of a second wavelength is then transmitted through an optical fiber (13), to the compact optical transceiver from a direction opposite that of the light generated by the laser diode (3). The light transmitted from the optical fiber (13) is then transmitted and output through ferrule (11), attachable to the optical fiber and attached in a second, V-shaped, groove of the ceramic mounting block (1). The light of the second wavelength is output to the beamsplitter (7) and is deflected through a bore hole (21) in the ceramic mounting block to a detector (9) abutting the bottom of the mounting block. Optionally, a blocking filter (15) can be included between the detector and the optical fiber end face for blocking light of any wavelengths different from the first and second wavelengths, from reaching the detector (9).
