Silicon waveguide asymmetric Y junction mode multiplexers and demultiplexers are
demonstrated for applications in on-chip mode-division multiplexing (MDM). We measure …

Major trace gases have absorption lines in mid-IR. We propose silicon-on-sapphire
waveguides at mid-IR for gas sensing based on evanescent field absorption. This can …

Second-harmonic generation is demonstrated using grating-assisted quasi-phase matching,
based on waveguide-width modulation or mode-shape modulation. Applicable to any thin …

Although silicon does not possess a dipolar bulk second order nonlinear susceptibility due
to its centro-symmetric crystal structure, in recent years several attempts were undertaken to …

We report the experimental demonstration of a modulation instability (MI) process assisted
by a periodic dispersion modulation in an optical fiber. We observe the spontaneous growth …

Mode-division-multiplexing (MDM) and wavelength-division-multiplexing (WDM) are
employed simultaneously in a multimode silicon waveguide to realize on-chip MDM and …
