The COC-287 from SemiNex Corporation is a Semiconductor Optical Amplifier that operates at a wavelength of 1550 nm. It delivers an output power of 0.375 W and has a 3dB bandwidth of 80 nm. This optical amplifier has an aperture width of 4 μm and aperture height of 1 μm. It has a gain of 32 dB and beam exit angle of 19.5 deg. This optical amplifier has a polarisation extinction ratio of 18 dB and beam divergence of 30 deg (fast axis) & 20 deg (slow axis) at FWHM. 

The COC-287 has a noise figure of 7 dB and front & rear face reflectivity of up to 0.1%. It uses a tilted straight waveguide and has a chip width of 500 μm. This optical amplifier requires a DC supply voltage of 2 V and consumes 1 A of current. It is available in a chip on carrier (COC) package and is ideal for optical fiber communications, coherent LiDAR, free space communications & network test equipment applications.
