Abstract
An improved optical packet address detector which is capable of enabling a high speed packet switching network of 100 Gbps, which includes a glass substrate having a mirror disposed at the back side thereof; a channel optical waveguide formed on the glass substrate and extended in a predetermined direction; a plurality of grating couplers spaced-apart on the channel optical waveguide for dispersing a packet signal beam passing through the channel optical waveguide into the inside of the glass substrate; an optical absorber attached to one end of the channel optical waveguide for absorbing part of the packet signal beam which is not dispersed by the grating coupler; a reflective lens spaced-apart from the optical absorber by a predetermined distance and formed on the glass substrate for focusing the signal beam dispersed by the grating coupler and reflected by the mirror; and a detector spaced-apart from the reflective lens and formed on the glass substrate for detecting the signal beam passing through the reflective lens and the mirror.
