摘要： A collimator for use at multiple wavelengths includes an optical fiber and a gradient index lens positioned at a constant distance with respect to an end of the optical fiber. The gradient index lens has a chromatic aberration at a selected pitch less than 0.01 over a selected range of the infrared spectral region.

摘要： A polarization dependent isolator includes a Faraday element, a linear polarizer positioned at a first end of the Faraday element to polarize light entering the first end of the Faraday element, and a single polarization fiber positioned at a second end of the Faraday element to receive light emerging from the second end of the Faraday element. A laser module includes a semiconductor laser diode, a Faraday element positioned adjacent the semiconductor laser diode, a linear polarizer positioned at a first end of the Faraday element nearest to the semiconductor laser diode to polarizer light passing from the laser diode to the first end of the Faraday element, and a single polarization fiber positioned at a second end of the Faraday element furthest from the semiconductor laser diode to receive light emerging from the second end of the Faraday element, wherein the single polarization fiber also serves as coupling output fiber for the laser module.
