Title:
WAVELENGTH MULTIPLEXING OPTICAL RECEIVER MODULE
Document Type and Number:
WIPO Patent Application WO/2018/074705
Kind Code:
A1
Abstract:
The present invention relates to a wavelength multiplexing optical receiver module, and more particularly, to a wavelength multiplexing optical receiver module that can be manufactured into a compact size by forming the optical receive module into a package structure without requiring a separate sealed package. The wavelength multiplexing optical receiver module, according to the present invention, comprises: an optical connection portion for connecting an optical connector positioned at the end of an optical line and the optical receiver module; an optical package portion for separating optical signals received from the optical connection portion into optical signals for each wavelength, and then collecting and reflecting each of the separated light signals; an amplification element portion for receiving the optical signals reflected by the optical package portion and converting same into electric signals; a printed circuit board for transmitting electric signals converted through the amplification element portion to an external circuit; and a silicon substrate provided with a groove portion so that the constituent elements of the optical package portion is assembled thereon, and with a deep groove of which the bottom is open so as to cover the constituent elements of the amplification element portion, wherein the gap between two sides of the printed circuit board and the silicon substrate is adhered so as to be sealed through flip chip bonding.
