Mid infrared silicon photonic integrated components, namely grating couplers, strip and slot waveguides, slotted and un-slotted photonic crystal waveguides, photonic crystal microcavities are experimentally demonstrated in silicon-on-sapphire. Application in trace gas sensing is experimentally demonstrated. Progress towards monolithic integration of lasers and detectors are discussed.
We demonstrate an efficient adiabatic mode converter for coupling light into a silicon slot photonic crystal waveguide with slot width as large as 320nm. The loss of the mode converter is measured to be 0.08dB.
We demonstrate an EO polymer based traveling-wave MMI-fed directional-coupler modulator. High-speed and linear operation is demonstrated with bandwidth-length product of 125GHz·cm, the 3-dB electrical bandwidth of 10GHz, and the SFDR of 110±3dB/Hz2/3.
We demonstrate for the first time stamp printing of silicon nanomembrane based photonic devices onto flexible substrate utilizing protection layer and suspended configuration. The propagation loss of the transferred waveguide is ∼1.1dB/cm.
