    摘要: The ferrule part 16 comprises ferrule 60, first and second optical fibers 62 and 64, and optical filter 68. Ferrule 60 has first and second end surface 60a and 60b, ferrule insertion hole 60c, and groove 68. Ferrule insertion hole 60c extends along a first axis, and accommodates first and second optical fibers 62 and 64. Groove 66 extends along a second axis crossing the first axis, and extends so as to extend across ferrule 60. Groove 66 is provided along a plane defined by the second axis and a third axis perpendicular to the first and second axes. Optical filter 68 can reflect a part of light incident on one surface 68b of the pair of surfaces of optical filter 68, and can transmit a part of the light incident on other surface 68a.

    摘要: Besides the central pn-junction and the central electrode, a PD chip has a peripheral pn-junction and a peripheral electrode which do not appear on the sides. The ends of the peripheral pn-junction are covered with a protection layer for preventing self-shortcircuit. A reverse bias is applied to the peripheral electrode for making a wide depletion layer beneath the peripheral pn-junction. Extra carriers generated by peripherally-incidence rays are fully absorbed by the peripheral depletion layer and annihilated by the reverse bias.

    摘要: A half-transmittance photodiode usable as a photodetector in receivers for “ping-pong transmission” is improved in temperature characteristic, so that a half-transmittance photodiode usable at low temperatures is available. A p-n junction is formed in a buffer layer, not in an absorption layer.
