17 January 2011Wavelength tunable laser diodes with Si-wire waveguide ring resonator wavelength filters
We fabricated wavelength tunable laser diodes consisting of ring resonator wavelength filters with Si-wire waveguides.
More than 45 nm wavelength tuning operation was obtained by about 100 mW heating power. We also measured spectral
linewidth of the tunable laser, and observed about 200 kHz of spectral linewidth.
