High power single mode photonic integration

High power single mode lasers with linewidths less than 500 kHz and CW output powers of 200 mW or higher have been integrated with additional optoelectronic components for value-added functionality at O-band, C-band and U-band wavelengths. Several different photonic integration techniques are described with results presented. High power functionalities including optical attenuation, amplification, wavelength multiplexing, and wavelength tuning at these high powers are described.
