Optical multi/demultiplexer device, optical wavelength selective filter and method of making filter

2005

Optical multi/demultiplexer (4) device comprising a substrate, a plurality of wave guides (45, 46, 47, 48) on a surface of said substrate, a plurality of selective wavelength filters (452, 462, 472, 482). Each of said plurality of filter is able to transmit a first predetermined band of wavelengths (PB') and to reflect a second predetermined band (SB'). Each one of said plurality of filter comprising a plurality of transverse cuts (4521, 4522, 4523) provided on said waveguide disposed in predetermined positions. Said cuts forms a plurality of transmissive couple providing said first predetermined band and a plurality of reflective couple providing said second predetermined band. Said transm…

Wavelength-flattened directional couplers for mirror-symmetric interferometers

2005

In the context of guided optics, we derive, analytically and geometrically, a rigorous general criterion to design wavelength insensitive interferometers with mirror symmetry, which are needed for wavelength multiplexing/demultiplexing. The criterion is applied to a practical case, resulting in an interferometer that works on a band wider than 70 nm.
