An optical device includes a substrate on which is defined at least one primary waveguide () defining a loop reflector, that has first and second directional couplers, and a Mach-Zehnder interferometer intercalated between the first and second directional couplers and arranged for compensating a wavelength dependence of the first and second directional couplers.

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

The present invention concerns a method for controlling the emitting wavelength of a laser source () for a passive optical network, the laser source () comprising:

Method for controlling the wavelength of a laser source

A coupler/splitter including two neighboring coplanar waveguide portions extending in a same direction, the first portion having a constant cross-section, the second portion having a variable cross-section so that the effective index of the second waveguide portion varies, in the upstream-to-downstream direction, from a first lower value to a second value higher than the effective index of the first portion, in adiabatic coupling conditions.

Polarization splitting optical coupler having an interposed guide segment extending between first and second coplanar waveguides
