Dense photonic integration requires miniaturization of materials, devices and subsystems, including passive components (e.g., engineered composite metamaterials, filters, etc.) and active components (e.g., lasers, modulators, detectors). This paper discusses passive and active devices that recently have been demonstrated in our laboratory and design, fabrication and testing of nanolasers constructed...
We demonstrate 448 Gbit/s transmission using CMOS silicon photonic, hybrid-integrated, full-band tunable lasers as transmit and local oscillator for 28 GBaud DP-16QAM. Marginal system performance differences were measured when compared with conventional commercially available lasers, proving suitability for coherent applications.
We demonstrate novel transverse and longitudinal optical forces that facilitate self-alignment between two parts of a waveguide broken by an offset and a gap. We analyze two-dimensional configurations and extend the discussion to three-dimensional systems.
