Optical assembly

摘要

An optical device has a first frame element and second frame element. At least portions of a plurality of optical fiber pairs of an array each including an exposed end are arranged between the two frame elements. A region is defined between opposing surfaces of the two frame elements to hold the optical fibers. When holding the fibers, the two frame elements cooperate to positionally align and orient the exposed ends of each of the optical fibers for at least one of transmitting and receiving light. An optical system with the device includes a TAP photodiode array such that a portion of light is transmitted from at least a pair of input optical fibers to a corresponding pair of photodiodes of the array, and a portion of light is reflected back from an optical filter to output optical fibers corresponding to the input optical fibers.

1. An optical device comprising:
a first frame element and a second frame element each having a surface; a plurality of pairs of optical fibers, respective portions of the plurality of pairs of optical fibers being held in the region defined by the first and the second frame elements, wherein, when the first and the second frame elements are arranged opposing each other, the surfaces of the first and the second frame elements oppose each other to define a region therebetween to receive and hold respective portions of the plurality of pairs of optical fibers in an array, each of the portions having an exposed end, and wherein when the first and second frame elements hold respective portions of the plurality of pairs of optical fibers in the array, the first and the second frame elements together cooperate to positionally align and orient the exposed ends of each of the optical fibers such that centers of the exposed ends of each of corresponding pairs of the optical fibers are diametrically opposed about a common center point and such that, for each of the corresponding pairs of optical fibers, when light is transmitted from the exposed end of one fiber of a corresponding pair and at least a portion of the transmitted light is reflected from an at least partially reflective object arranged relative to the optical device, at least a portion of the transmitted light is received by the other fiber of the corresponding pair.
