    Abstract: The present invention is a hybrid cell that utilizes a PBS pair in conjunction with a wedge tuner and a crystal to achieve a more stable interleaver. A first PBS splits an incoming optical signal into two orthogonally polarized beams which follow different optical paths through the cell. The length of the wedge tuner and crystal are selected such that the periodicity of the cell is approximately inversely proportional to the free spectral range at a target frequency. The length of the wedge tuner and crystal are also selected such that there is no change in an optical path difference between the two optical paths with respect to a change in temperature over an operating temperature range.

    Abstract: The present invention provides low cost methods and apparatuses for filtering out polarized light reflections in a free-space optical isolator. In one embodiment, a laser directs a non-polarized optical signal through a series of polarizers and rotators in order to isolate an optical signal having a specific polarization. The present invention also includes a quarter-wave plate placed in series with the rotators and polarizers, to help filter away reflections occurring while the signal passes through free space. The inclusion of the quarter-wave plate helps filter away a greater amount of near-end reflections from going back to the laser, even with the use of low cost polarizers. Accordingly, the present invention can polarize an optical signal more efficiently than with prior methods, and at a much lower cost.

    Abstract: An optical interleaver for use in a range of telecommunications applications including optical multiplexers/demultiplexers and optical routers. The optical device includes an optical processing loop which allows multi-stage performance characteristics to be achieved with a single physical filtration stage. Optical processing on the first leg and second legs of the loop is asymmetrical thereby improving the integrity of the optical signals by effecting complementary chromatic dispersion on the first and second legs. A fundamental filter cell within the interleaver filters optical signals propagating on each of the two legs of the optical loop which intersects the fundamental filter cell.
