Abstract

Couple Mode Theory is the fundamental design of new optical device development. The basic concept is wavelength separation point which evanescent field plays an important to distribute the energy among the coupled waveguide and the desire function of device is determined by coupling length. However the wavelength channel spacing will influence the length of coupling. The bigger channel spacing will take longer coupling length to enable the signal been separated. In this paper, we introduced a new modification of waveguide architecture to achieve the complete wavelength separation with reduction of coupling length required. As a result, we able to design one demultiplexer/multiplexer device which can separate four CWDM wavelengths. This is new approach of optical device design and development.
