Title:
VARIABLE WAVELENGTH LASER DEVICE AND VARIABLE WAVELENGTH LASER DEVICE PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/235317
Kind Code:
A1
Abstract:
This variable wavelength laser device comprises a first semiconductor chip having first and second waveguides disposed in parallel, and a second semiconductor chip having an optical circuit optically connected to the first and second waveguides that, in conjunction with the first and second waveguides, constitute a resonator. Each of the first and second waveguides has two or more surface electrodes. The second semiconductor chip has a plurality of electrodes joined to the surface electrodes of the first and second waveguides.
