Integrated photonic devices that are less sensitive to external influences and methods for reducing sensitivity

Title:

Integrated photonic devices that are less sensitive to external influences and methods for reducing sensitivity

Document Type and Number:

Japanese Patent JP6342651

Kind Code:

B2

Abstract:

Photonic device (100) having a wavelength-dependent transmission or filter characteristic, comprising: a Splitter Polarization Rotator (11) receiving polarized light (1) and providing a first resp. second wave (2, 3); a first resp. second waveguide arm (12, 13) connected to the SPR for propagating a first resp. second polarization mode (TM, TE) of the first resp. second wave (2, 3), the second polarization mode (TE) being different from the first polarization mode (TM); and a Polarization Rotator and Combiner (14) for combining the propagated first resp. second waves (2, 3); wherein the dimensions of the first and second arm (12, 13) are selected to cancel the influence of an external effect on the wavelength-dependent characteristic. Method for reducing the sensitivity of said integrated photonic device, comprising splitting a polarized light beam (1), and propagating light waves(2,3) of different polarity through two waveguide arms of specific dimensions, and recombining them.
