Patent CA-2269231-A1 (CA)
Inventor: XU JINGMING
IPC: H01S3/063
Filed: 1999-04-16
Abstract: The present invention provides self-collimating multiwavelength lasers (MWL) including a planar gain medium with a resonance cavity defined by superimposed gratings. These laser devices are characterized by lasing wavelengths with multiple peaks in their reflectance spectra defined by the superimposed gratings. The gratings also limit beam divergence, producing self-collimated multiwavelength output, with the potential for high power.  These devices can be implemented in any planar gain medium in which multi-peak gratings can be produced, including but not limited to semiconductors and doped glasses. The self-collimated MWL's disclosed herein have applications in areas such as DWDM (dense wavelength division multiplexing) communications systems, free-space uses such as interconnects, range-finding, and inter-satellite infrared communication. In one aspect the device is a multiwavelength ring cavity laser including a planar gain medium with two orthogonal pairs of supergratings (SG)A and B, which emulate the superposition of M and N single-pitch gratings respectively. SG-A has a set of M diffraction wavelengths that depends on the incident angle .theta.; a similar dependence on .PHI. = .theta.-90° exists for the set of N diffraction wavelengths of SG-B.  Wavelength-angle pairs common to both SG-A and SG-B will be resonant within the cavity as a whole. When combined with optical gain, the result is lasing at M by N wavelengths, collimated at a well-defined output angle.

Title: Encoded stream splicing device and method, and an encoded stream generating device and method
Inventor: NEGISHI SHINJI
IPC: H04N21/44
Filed: 1998-10-05
Abstract: A stream converting circuit converts the stream type of an original encoded stream transmitted as a transport from a master station into an elementary stream. The converted original encoded stream is supplied to a stream analyzing circuit of a stream splicer. The stream analyzing circuit analyzes the syntax of the original encoded stream received to extract, from the original encoded stream, data elements such as data "vbv_delay" representing the initial state of a VBV buffer, a flag "repeat_first_field" indicating whether a repeat field is to be generated or not during decoding, and a flag "top_field_first" indicating whether the first field is a top field or a bottom field, and then supplies these data elements to a splice controller, which in turn supplies these data elements to the stream processor. The stream processor, according to the data elements, rewrites data elements of a replacement encoded stream.
