Efficient nonlinear silicon photonics rely on phase-matching through fine waveguide dispersion engineering. We experimentally demonstrate dynamic dispersion tuning of 800 ps/nm/km in a silicon waveguide ring resonator, by using microelectromechanical actuation of an adjacent suspended waveguide rim.
Thanks to its nonlinear-, electro- and acousto-optical and piezo-response properties [1], lithium niobate (LiNbOs, LN) is widely used for many photonic applications. The high refractive index contrast offered by recently available thin film lithium-niobate-on-insulator (LNOI) platforms, provides new possibilities for miniaturizing LN-based integrated optics structures such as submicron waveguides...
We experimentally demonstrate the first MEMS tunable photonic fiber-to-waveguide grating coupler, and apply it to electrostatically optimize the light coupling between an optical fiber and an on-chip silicon photonic waveguide. Efficient and stable fiber-to-chip coupling is vital for combining the high optical quality of silica fibers with the integration density of silicon photonics. Our device has...
We demonstrate the first uncooled single-nanowire-based infrared bolometer to detect sub-mW optical signals up to MHz frequencies. The bolometer consists of a Pt nanowire on a suspended silicon hybrid-plasmonic cavity, and exhibits enhanced optical responsivity compared to nanowires on unstructured and non-suspended substrates. Low-cost monolithically integrated infrared detectors are needed for the...
We demonstrate a MEMS tunable silicon photonic ring resonator with a 20 µm radius and a 5 nm free spectral range (FSR) for wavelength selection in reconfigurable optical networks. The device shows a loaded Q of 12000, and 300 pm tuning range at a wavelength of 1544 nm.
We experimentally demonstrate a low-power MEMS tunable photonic ring resonator with 10 selectable channels for wavelength selection in reconfigurable optical networks operating in the C band. The tuning is achieved by changing the geometry of the slot of a silicon slot-waveguide ring resonator, by means of vertical electrostatic parallel-plate actuation. Our device provides static power dissipation...
We demonstrate a method for the fast and simple packaging of silicon sensors into a microfluidic package consisting of the recently introduced OSTE polymer. The microfluidic layer is first microstructured and thereafter dry-bonded to a silicon photonic sensor, in a process compatible with wafer-level production, and with the entire packaging process lasting only 10 minutes. The fluidic layer combines...
