摘要： Provided is an athermal external cavity laser (ECL), whose output optical power and output wavelength can be kept regular irrespective of temperature changes without using additional temperature controlling components. The ECL comprises: a semiconductor amplifier; an optical fiber comprising a core in which a Bragg grating is formed and a cladding surrounding the core; and a thermosetting polymer that fixes the optical fiber to a ferrule and has a negative thermooptical coefficient, wherein the thickness of the cladding surrounding the core in which the Bragg grating is formed is smaller than the portion of the cladding surrounding the portion of the core where the Bragg grating is not formed, and the thermosetting polymer the negative thermooptical coefficient surrounds the cladding. The ECL does not need additional temperature controlling components and thus can be manufactured compact and at low cost, and thus can be used as a light source of a dense wavelength division multiplexing (DWDM) system in designing economical WDM passive optical networks (PON).

摘要： Disclosed herein is a loop-back Wavelength Division Multiplexing Passive Optical network (WDM-PON). The loop-back WDM-PON includes a coupler, a terminal receiver, and a reflective semiconductor amplifier. The coupler branches a downstream signal, which is transmitted from a central office, into first and second downstream signals. The terminal receiver receives and converts the first downstream signal into electrical signal and provides the electrical signal to a subscriber. The reflective semiconductor optical amplifier flattens modulated optical power of the second downstream signal input to the RSOA and re-modulating the flattened signal by changing driving current in response to upstream data.
