Five-output optical power divider based on multichannel coupled waveguide structure

A novel five-output optical power divider with multichannel coupled waveguide structure has been developed. This device has been designed and simulated by the beam propagation method for evenly distributed power output and fabricated by the RF-sputtering technique on SiO₂ based material. Experimental observation of the output power distribution at a wavelength of 1.31 mu m indicated a port to port variation of less than 10% from the designed specification.
