ABSTRACT:
A low-loss optically active device is provided by forming a lower clad layer using linear polymer on a substrate capable of transmitting ultraviolet (UV) light, forming a non-linear polymer core region of a waveguide region; forming a linear polymer core region on opposite sides of the non-linear core region, and forming an upper clad layer on the lower clad layer and linear and non-linear core regions of the waveguide region. The waveguide is formed using non-linear polymer only at the region where the non-linear effect such as optical modulation or optical switching occurs, and is formed using linear polymer at the remaining regions, thereby minimizing the overall waveguiding loss of the device.
