Post-Fabrication Phase Correction of SOI 4 × 4 MMI-Based 90° Optical Hybrids via Femtosecond-Laser Trimming. [PDF]
NanophotonicsFabrication‐induced phase deviations in integrated silicon 4 × 4 MMI‐based 90° optical hybrids are compensated through localized femtosecond‐laser trimming. Permanent refractive‐index modification enables device‐specific postfabrication phase control, reducing phase deviations to within ± 5° across the full C‐band (1530–1565 nm) while maintaining a ...

Customized Itinerant Frequency Combs by Cascaded Nonlinear Effects. [PDF]
Adv Sci (Weinh)A cascaded third‐order nonlinear system generates an itinerant frequency comb with the comb center frequency decoupled from the cavity resonance. This enables arbitrary spectral scaling, flexible spacing adjustments, and real‐time central‐frequency engineering, allowing comb splicing and subdivision. The resulting versatility and reconfigurability open
