Silicon Photonics: A New Twist on Light
IME researchers have developed a highly efficient and compact wideband silicon-waveguide-based polarization rotator to enhance the performance of Si photonic circuits. For high index-contrast waveguides, fabrication error of just a couple of nanometers would result in undesirable birefringence, which is a major roadblock to manufacturing. Small core silicon-waveguide based Si photonics are particularly susceptible to the effects of polarization. The IME-developed rotator allows different launching conditions that would enable new designs of polarization splitter and rotator. The proposed rotator is expected to accelerate the adoption of emerging Si photonics technology into mainstream optoelectronics applications.
