摘要： A light source system for fiberoptic networks is presented. The system has a laser light source, an optical circulator, an optical fiber section having at least one fiber Bragg grating, and an output port. The optical circulator receives light through its first port and passes the light to the circulator's second port and light received through the second port is passed to the circulator's third port. The first port is connected to the light source. The optical fiber section is connected to the second port and the fiber Bragg grating has a reflectivity centered about a predetermined wavelength. The third port, which is unconnected to the light source, is connected to the output port of the system. Light from the output port has the predetermined wavelength with significantly reduced ASE.

摘要： A beam steering module comprised of a mirror stack array in close proximity to a collimator array controllably steers photons along two axis and in a direction substantially less than 90 degrees to the collimator orientation. Several configurations of the module are described using single and double axis mirror rotation and relay optics. Optical telecommunications switches are shown using modules coupled to each other along flat and curved surfaces, with and without use of fold mirror and enabling a plurality of configuration options including photodetector optical power monitoring schemes that require no external power taps.

摘要： A mechanically stable self-aligned optical switch having a low insertion loss is achieved by employing two silica optical structures containing a plurality of waveguides. The waveguides within each structure are arranged in a common plane. It is possible to achieve such silica optical structures by cleaving a monolithic silica optical structure. In one embodiment, the structures are disposed on respective flat surfaces of moveable and fixed bases that are aligned in a common plane. The structures are further positioned with their cleaved edges adjacent to and facing one another. In this manner, the waveguides of the cleaved structures are effectively self aligned in the direction normal to the flat surface of the bases. In operation, the moveable base moves in the direction along the cleaved edges to selectively provide connections between the waveguides in each structure.

摘要： A method of assembling an optical device for coupling optical fibers to a corresponding number of input/output ports of a stack of optical elements includes utilizing at least one controllable multi-state optical element to selectively switch the optical coupling among the ports. The controllable multi-state element is one element within a stack of polarization-manipulating elements having a configuration that allows the condition of the multi-state element or elements to dictate the optical coupling among the ports. In the preferred embodiment, the multi-state element is a Faraday rotator. The method may be used in either or both of a quality control application or a fiber-to-port alignment application. In the quality control operation, the stack of polarization-manipulating elements is tested to verify proper operation with respect to separating and selectively recombining polarization components of input beams. In the fiber-to-port alignment application, the fibers on the same side of the stack are first fixed in a parallel relationship with a known center-to-center distance that is equal to the center-to-center distance between corresponding ports of the stack. By optically aligning one of the fibers on the forward side of the stack with the fibers on the rearward side of the stack, at least one other fiber is automatically brought into registration with its corresponding port.

摘要： Encoders and decoders for applying composite codes to optical data signals include encoders (211, 231) and decoders (243, 261) for applying both subcodes and supercodes. The subcodes have a duration selected as less than or equal to an interchip duration or a chip duration of the supercodes. The encoders (211, 231) and decoders (243, 261) ("coders") include fiber Bragg gratings configured to encode or decode a subcode, a supercode, or a composite code. By coding with a subcode coder, a coder is reconfigurable by selecting different subcodes or supercodes. Communication systems and methods using composite codes are also described.
