Abstract :
A widely tunable coupled-ring-reflector filter based on compact polymer waveguide is fabricated and the characteristics are measured. The ring radii of two rings are slightly different, which are 150 and 156 m, to achieve wide tuning of 43 nm using a low heating current as small as 37 mA.
