Optical device with integrated reflector(s) comprising a loop reflector integrating a mach-zehnder interferometer

摘要

An optical device (1) comprises a substrate (2) on which is defined at least one primary waveguide (3 1 , 3 2 ) defining a loop reflector, comprising first (4 1 ) and second (4 2 ) directional couplers, and a Mach-Zehnder interferometer (5) intercalated between the first (4 1 ) and second (4 2 ) directional couplers and arranged for compensating a wavelength dependence of the directional couplers (4 1 , 4 2 ).
