Embodiment Construction

[0025] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. For the purpose of brevity, detailed descriptions of incorporated known functions and structures will be omitted here since it would obscure the subject matter of the present invention.

[0026] FIG. 3 shows a schematic diagram of a bi-directional optical communication module 200 with a reflector according to a preferred embodiment of the present invention. As shown in the figure, the bidirectional optical communication module 200 includes a multiplexer 203 , a reflection slot (shown as 249 in FIG. 5 ), and optical waveguides 231 , 232 , 233 and 234 . The multiplexer 203, reflective groove 249, and optical waveguides 231, 232, 233, and 234 are formed by stacking the lower cladding layer 202 on the silicon or polymer substrate 201, and stacking the core layer (not shown) on the lower cladding layer. On the cladding layer 202, the core layer is etch...

Abstract

A bidirectional optical communication module capable of precisely controls the location of a reflective surface of the reflector is disclosed. The module includes: an input waveguide for inputting an optical signal; a reflector including a reflective groove formed by a photolithography process such that the groove is extended from one end surface of the bidirectional optical communication module to a connection waveguide, and a reflective layer formed on a base surface formed in the reflective groove so as to reflect the optical signal inputted from the input waveguide; and an output waveguide for outputting the optical signal reflected by the reflector. The connection waveguide is configured to transmit the optical signal inputted from the input waveguide to the reflector and output the optical signal reflected by the reflector to the output waveguide.

Description

technical field [0001] The invention relates to a bidirectional optical communication module, in particular to a bidirectional optical communication module with a reflector used in an optical communication network. Background technique [0002] Bi-directional optical communication modules are used to multiplex or demultiplex optical signals in optical communication networks. Bidirectional optical communication modules are typically produced by sequentially laminating a lower cladding layer, a core layer with a prescribed pattern, and an upper cladding layer on a silicon or polymer substrate. [0003] In general, light sources for generating optical signals and photodetectors for detecting received optical signals are located at the transmission and reception terminals of an optical communication network. The bidirectional optical communication module is provided with a light source and a photodetector arranged on a single substrate, and transmits or receives optical signals...
