In particular, the achievable side-mode threshold difference of the V-coupled-cavity laser is greatly increased compared to the prior-art Y-coupled-cavity laser, and it becomes comparable to that of DFB lasers. The complex fabrication process for DFB grating is not required and the wavelength ...

semiconductor lasersWe present a photonic integrated circuit (PIC) composed of two strongly coupled lasers. This PIC utilizes the dynamics of mutual injection locking to increase the relaxation resonance frequency from 3 GHz to beyond 30 GHz.missing...

In summary, we fabricated GaInAsP lasers with a semiconductor/air DBR by the ICP etching and obtained the normalized lasing threshold of 3mA/渭m. The FDTD simulation indicates that the crucial factor for high reflectivity is the sidewall anglemuch higher than 85 degrees. Now, we are optimizing...
In conventional DFB and DBR lasers, light is removed through an end facet and the output beams have dimensions entirely controlled by the vertical (i.e., normal to the surface) (x) and lateral (y) size and the composition of the guiding structure. Such output beams are typically have too...
