摘要： A nonreciprocal optical element and method for operating it to effect separate control of intensity and phase (or optical path length) of counter propagating beams over a very wide range. The nonreciprocal optical element includes a circulator for routing a first signal from a first port to a second port and a second signal from the second port to a third port, a third signal from the third port to a fourth port and a fourth signal from the fourth port to the first port; a first mirror for reflecting a signal output by the second port back into the second port; and second mirror for reflecting a signal output by the fourth port back into the fourth port. Polarization rotation elements such as quarter-wave plates are disposed between the mirrors and the second and fourth ports to preserve the polarization of the input beams. Filters are disposed between these ports and mirrors to adjust the transmittance of the input and output signals. An arrangement is included for translating the positions of the mirrors relative to the ports to adjust the phase of the output signals. Independent spectral control is effected by providing a Bragg grating, interference filter or other spectral filter between the second or fourth ports and the mirror associated therewith.

摘要： An optical arrangement and method of filtering include a beam splitter that accepts an incident beam and transmits light from the incident beam of a first polarization and reflects light from the incident beam of a second polarization. The transmitted light is a first beam and the reflected light is a second beam. A first spectral filter, receives the first beam, reflects a first spectral band of the first beam, and transmits the remainder of the first beam. A second spectral filter receives the remainder of the first beam and reflects a second spectral band of the first beam. The first and second spectral filters can also receive the second beam and reflect similar first and second spectral bands. The spectral bands are then returned to the beam splitter, where they may be directed toward a dispersal element or an array of photodetectors.

摘要： A method and apparatus for measurement of individual phases of beams from a beam steering laser array relative to a reference laser beam. The disclosed method and apparatus is based on the use of a partially reflecting ellipsoidal reflector or dual paraboloidal reflector having two focal areas to make an image of the laser array located in one of the focal areas appear at the other focal area. Illumination of this image with a phase modulated beam from a reference laser coherent with the laser array allows the application of dithering techniques to measure individual phases of beams from array. Any laser beam in the array or a separate laser coherent with the laser array can be used as a reference beam. In addition, the partially reflecting ellipsoidal reflector or dual paraboloidal reflector can provide protection for the beam steering laser array from environmental impacts or damage.
