Title Optical NEP in hot-electron nanobolometers Type Journal Article
Year 2010 Publication Abbreviated Journal
Volume Issue Pages (up) 1-7
Keywords HEB, Ti, NEP, femtowatt, SAFARI, SPICA, 650 GHz, 0.65 THz, 460 um, twin slot antenna, SQUID readout
Abstract For the first time, we have measured the optical noise equivalent power (NEP) in titanium (Ti) superconducting hot-electron nanobolometers (nano-HEBs). The bolometers were 2{\mu}mx1{\mu}mx20nm and 1{\mu}mx1{\mu}mx20nm planar antenna-coupled devices. The measurements were done at {\lambda} = 460 {\mu}m using a cryogenic black body radiation source delivering optical power from a fraction of a femtowatt to a few 100s of femtowatts. A record low NEP = 3x10^{-19} W/Hz^{1/2} at 50 mK has been achieved. This sensitivity meets the requirements for SAFARI instrument on the SPICA telescope. The ways for further improvement of the nano-HEB detector sensitivity are discussed.

Title Monolithic InP multi-wavelength coherent receiver Type Conference Article
Year 2010 Publication Conference on optical fiber communication, collocated national fiber optic engineers conference Abbreviated Journal Conf. OFC/NFOEC
Volume Issue Pages (up) 1-3
Keywords InP balanced detector, waveguide grating, polarization splitter, from chiralphotonics
Abstract We propose and demonstrate a novel four-channel monolithic polarization-diversity dual-quadrature coherent receiver with balanced detection in InP. It uses an interleave-chirped arrayed waveguide grating that acts simultaneously as a demultiplexer, 90° hybrid, and polarization splitter.

Title 20-μm-pitch eight-channel monolithic fiber array coupling 160 Gb/s/channel to silicon nanophotonic chip Type Conference Article
Year 2010 Publication Conf. OFC/NFOEC Abbreviated Journal Conf. OFC/NFOEC
Volume Issue Pages (up) 1-3
Keywords spot size converters, SSC, optical waveguides, optical fiber waveguides, ultra-dense silicon waveguide arrays, silicon waveguides, waveguide arrays, from chiralphotonics
Abstract A multichannel tapered coupler interfacing standard 250-μm-pitch low-NA polarization-maintaining fiber arrays with ultra-dense 20-μm-pitch high-NA silicon waveguides is designed, fabricated, and tested, demonstrating coupling losses below 1 dB and injection bandwidths of 160 Gb/s/channel.
