Tunable laser comprising a multiple ring resonator and higher order mode blocking filter |
| abstract |
A tunable laser has a multiple ring resonator comprising a plurality of ring resonators having respective ring-shaped waveguides and respective different optical path lengths, an input/output side optical waveguide coupled to the multiple ring resonator, an optical input/output device such as a laser diode coupled to the input/output side optical waveguide, a reflection side optical waveguide coupled to the multiple ring resonator, an optical reflector coupled to the reflection side optical waveguide, a wavelength varying mechanism for changing the resonant wavelength of the multiple ring resonator, and a filter for preventing light in high-order modes from being introduced into the multiple ring resonator and for propagating light in a fundamental mode in the multiple ring resonator. |
