Molloy, Andrew W2004-12-202005-03-102011-01-052005-03-102011-01-05b43751143http://hdl.handle.net/1885/42658A novel approach to the simultaneous multiplexing or de multiplexing of 3 wavelengths for coarse wavelength channel separation is based on the geometrical evolution and transformation of the modes of a single few-mode planar device. An input fundamental mode is transformed into a particular higher-order mode, depending on its wavelength, and then is transformed directly into the fundamental mode of a particular output port. The functionality of the device is quantified and its performance optimised through appropriate design. The device overall size is minimised, taking into account core spacing requirements for a fibre pigtailing, i.e. connecterisation of the input and output device arms to optical fiber.2113229 bytes358 bytesapplication/pdfapplication/octet-streamen-AUHonours thesisAdiabatic Coarse Wavelength De/Multiplexing for Optical Systems200410.25911/5d7a28949a83e
