| 20120057817 | LIGHT WAVE GUIDE WITH LOW REFLECTIVITY - An optical light splitter includes or is connected to at least two input waveguides ( | 03-08-2012 |
| 20110274439 | COMMUNICATION SYSTEM COMPRISING A TUNABLE LASER - A communication system includes a communication unit with a first part and a number of a second part, where the second part is arranged to be placed at the location of an end user, and where the first part is common for a number of second parts. The first part and the second part respectively include a laser, and each second part is connected with the first part by a fibre optic cable and a frequency filter, the first part and the relevant second part being arranged to exchange information by laser light. Each second part includes a tunable laser, the first part is arranged to analyze light received from a second part, and to transmit information to the second part while the first part is receiving light from the second part, and the information contains information for the second part that it should adjust, where required, its frequency or wavelength, and the second part thus is arranged to change its frequency or wavelength. | 11-10-2011 |
| 20110222816 | WAVEGUIDE FOR EXTRACTION OF LIGHT AT LOW LEVELS OF REFLECTION - A waveguide for the extraction of light at low levels of reflection arranged to guide light from an electro-optical component on a chip to a facet on the chip for extraction includes a first part and a second part. The first part ( | 09-15-2011 |
| 20110069726 | METHOD FOR SUPPRESSING SIDE MODES IN A TUNABLE LASER - Method for suppressing side modes during use of a tunable laser of MGY type, having an amplification section, a phase section and a reflector section having a Y-branched waveguide, with a first a second branch, where the laser operation point is defined by feeding a respective current through the phase section, the first and the second branch, where possible combinations of these currents span a three-dimensional space, in which elongated volumes define combinations of currents for which the laser is operated in the same mode and where two-dimensional sections, defined by holding the current through the phase section constant and varying the currents through the branches, through a certain of the volumes constitute modeflats. The two branch currents are controlled within a certain modeflat so that the laser operation point does not coincide with the centre of the modeflat, but is sufficiently far from the periphery of the modeflat for mode transitions not to occur, within a predetermined time period, as a consequence of changes related to ageing of the laser, leading to drift of the laser operation point. | 03-24-2011 |
