Abstract
In this study, we design and fabricate an optical interleaver using arrayed waveguide gratings (AWGs). The characteristic of AWGs which is a large channel spacing between two adjacent wavelengths in the same channel, so we can reliably through the tunable fiber Bragg grating (TFBG) to filter. Through the tunable FBG, the reflected wavelength signal, which we want to get, can be sent to the output port. We can also use the optical circulator (OC) to add the wavelength signal from the add port to join the original network routing. This system can also be used to achieve an all-optical multichannel reconfigurable optical Add/Drop multiplexer (ROADM) system.
