Abstract
Presently, silicon photonics is receiving considerable attention because it provides a promising platform for fabrication of highly integrated photonic devices. In addition, silicon photonic devices can be fabricated using the mature fabrication technologies of electric integrated circuits. We focused on an integrated light source and developed wavelength tunable lasers using silicon photonic technologies. The narrow spectral linewidth heterogeneous laser diode with high optical output power was realized for optical digital coherent communication systems[1]. The recent studies for expanding the availability of heterogeneous lasers will be presented.
