Abstract:
1. An integrated optical sub-assembly for a diplexer, comprising: a laser diode for outputting an optical signal, a lens located in front of the laser diode, for delivering the optical signal from the laser diode, an isolator for receiving the optical signal from the laser diode, through the lens, a glass ferrule for passing the optical signal, the glass ferrule being aligned along an extension of an axial line of the laser diode, the lens and the isolator and disposed such that one end of the glass ferrule faces the isolator and opposite end is connected to an optical fiber, a total internal reflection glass for reflecting an incident optical signal by an angle of substantially 50°-60°, the total internal reflection glass being disposed under the glass ferrule, and a receiver for receiving an optical signal from the total internal reflection glass, wherein the isolator is adhered to a front surface of the glass ferrule, such that the isolator is placed at a given distance from the laser diode.
