摘要： A quasi-achromatic configuration of two nonreciprocal optical rotators (25, 27) coupled by linear retardation elements (26, 28) based on total internal Fresnel reflection, such that wavelength or temperature effects on the optical rotator elements compensate one another to give quasi-achromatic isolation and/or temperature stability when this optical configuration is incorporated into an optical isolator or circulator. A quasi-achromatic optical isolator through which a light beam within a wavelength range about a nominal wavelength may propagate is made from a sequence of elements having a first plane polarizer (24) accepting said light beam as an input, said light beam then passing through in sequence, a first Faraday rotator (25), a first wave-length independent linear retardation element (26), a second Faraday rotator (27), a second wavelength independent linear retardation element (28), and said light beam exiting said isolator undiminished in intensity through a second plane polarizer (29). A quasi-achromatic optical circulator having first, second, third and fourth ports is provided such that said circulator may accept a light beam within a wavelength range about a nominal wavelength and direct it to a succeeding port. A light beam enters said circulator through a first polarizing beam splitter (44) adjacent to said first and third ports and passes through sequentially a first Faraday rotator (25), a first wavelength independent linear retardation element (26), a second Faraday rotator (27), a second wavelength independent linear retardation element (28) and a second polarizing beam splitter (49) adjacent to said second and fourth ports of said circulator, whereby said light beam is transmitted undiminished in intensity to the next succeeding port.

摘要： A birefringent optical wavelength multiplexer/demultiplexer (Fig. 2) includes a first polarization beam-splitter (PBS), a first reflector (TIR), a plurality of birefringent elements (C1, C2, C3), a second reflector (TIR), and a second polarization beam-splitter (PBS). The plurality of birefringent elements are so oriented that each element introduces an additional sinusoidal component to the transfer function of the device that tends to effectuate a flattened transfer function.

摘要： A telecentric optical fiber connector (13), shown in Fig. 1, wherein light from an optical fiber (11) is emitted from the connector lens (18) in a comparatively large diameter parallel beam (19), including two primary components: an integral optical quality plastic connector body (17) having an annular planar reference surface (26) substantially perpendicular to an optical axis (46) (Fig. 3). A convex lens surface (18) is molded, recessed inward from the reference surface (26). The body (17) is substantially cylindrical, with exterior means (55) (Fig. 4) thereabout so that it can be engaged with a similar body. The opposite axial end of the body (17) has a central cilindrical cavity (52) (Fig. 3) therein which extends to a point (16) which is one focal length from the lens surface (18). A fiber holder (14), which holds an optical fiber (11) centrally within an axial hole (29), abuts an end of the fiber (11) against the point (16) one focal length from the lens surface (18), and can be engaged with index-matching material.
