20150098678 | COMPOUND OPTICAL CIRCUIT SWITCH - A compound optical circuit switches and methods are disclosed. Two or more 1 | 04-09-2015 |
20150055202 | MULTICHANNEL OPTICAL POWER METER USING A SYNCHRONOUS SCANNER - Optical scanning systems and methods of controlling a resonant scanning mirror are disclosed. A rotatable mirror may oscillate about a rotation axis in response to a drive signal. A reference source may provide a reference light beam directed to the rotatable mirror. A reference detector may be disposed to receive the reference light beam reflected from the rotatable mirror twice during each oscillation of the rotatable mirror. A controller may set both an amplitude and a frequency of the drive signal based on an output of the reference detector. | 02-26-2015 |
20150036973 | MIRROR DRIFT COMPENSATION IN AN OPTICAL CIRCUIT SWITCH - Methods of operating an optical circuit switch and optical circuit switches are disclosed. To make a connection between a first port and a second port, baseline voltages may be determined, baseline voltages being voltages that, if respectively applied to one or more electrode coupled to a first mirror element uniquely associated with the first port and one or more electrode coupled to a second mirror element uniquely associated with the second port, cause the first and second mirror elements to rotate to make the connection in the absence of accumulated mirror element drift. Accumulated drift data associated with one or both of the first mirror element and the second mirror element may be retrieved from a memory. One or more of the baseline voltages may be modified based on the accumulated drift data to provide corrected voltages, and the corrected voltages may be applied to the electrodes. | 02-05-2015 |
20150036972 | MAKING LIGHTLESS CONNECTIONS IN AN OPTICAL CIRCUIT SWITCH - Methods of operating an optical circuit switch and optical circuit switches are disclosed. A command to make an optical connection between a first port and a second port may be received. A determination whether or not input signal light is present at the first port may be made. When light is present at the first port, an optical connection may be made between the first port and the second port. When light is not present at the first port, the optical circuit switch may wait until light is present at the first port before making the connection. | 02-05-2015 |
