Silicon Rib-waveguide based On-chip Optical Attenuator
Optica Advanced Photonics Congress 2022(2022)
摘要
A 30-µm length silicon rib-waveguide based on-chip optical attenuator is fabricated and experimentally demonstrated. For a wide range of wavelengths (1490-1590nm), the attenuator offers around 2.6 dB of attenuation at 1.5V.
