摘要： Embodiments of an optical assembly for use in polarization rotation applications are disclosed. In one aspect, an optical assembly includes a polarization beam splitter a rotational element and a path exchange mirror. The temperature, wavelength and manufacturing dependencies of polarization rotation of this optical assembly are minimal to nonexistent compared to conventional Faraday rotation assemblies as the optical fiber accepts only the desired rotation. As such these optical assemblies have no temperature and wavelength dependencies of the polarization rotation angle over broad temperature and wavelength ranges with minimal additional losses. In another aspect, the polarization dependence of reflection from the path exchange mirror is managed so as to minimize the polarization effect associated with oblique incidence.

摘要： A fiber-based, magneto-optic (MO) optical modulator or switch based on Sagnac interferometry is provided. The system uses a magneto-optic Faraday rotator (MOFR) to produce optical modulation with low magnetic fields. The Sagnac geometry allows for increased modulation at lower fields than traditional MO modulators. This switch uses the MOFR to create different states of polarization in counter-propagating waves, which results in interference at the output port. A magnetic field is used to control the amount of rotation in the state of polarization (SOP), and therefore, the ON-OFF extinction ratio.

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.
