WAVELENGTH DIVISION MULTIPLEXED-PASSIVE OPTICAL NETWORK APPARATUS
First Claim
1. A wavelength division multiplexed-passive optical network (WDM-PON) apparatus comprising:
- an optical source unit generating an optical signal;
an optical mux receiving the optical signal from the optical source unit through one end of the optical mux, multiplexing the optical signal, and outputting the multiplexed optical signal; and
a chirped Bragg grating connected to the other end of the optical mux,wherein the chirped Bragg grating again reflects the optical signal having passed the optical mux to re-input a certain portion of the optical signal into the optical mux and the optical source unit, and the optical mux performs a spectrum slicing on the re-inputted optical signal and operates the optical source unit using a channel wavelength of the optical mux as a main oscillation wavelength.

Abstract
Provided is a wavelength division multiplexed-passive optical network (WDM-PON) apparatus. The WDM-PON includes an optical source unit, an optical mux, and a chirped Bragg grating. The optical source unit generates an optical signal. The optical mux receives the optical signal from the optical source unit through one end of the optical mux, multiplexes the optical signal, and outputs the multiplexed optical signal. The chirped Bragg grating is connected to the other end of the optical mux. The chirped Bragg grating again reflects the optical signal having passed the optical mux to re-input a certain portion of the optical signal into the optical mux and the optical source unit. The optical mux performs a spectrum slicing on the re-inputted optical signal and operates the optical source unit using a channel wavelength of the optical mux as a main oscillation wavelength.
