This paper presents our discovery that self-rotation of Melan-a pigment cells can be induced by applying appropriate optical dielectrophoretic (ODEP) parameters. Under optically induced DEP force, which is generated by specific optical electrode patterns and with a band-width of AC bias frequencies, Melan-a cells can be trapped or repelled away from the optical electrodes. In addition, the self-rotation...
A high-speed pin-TWA photoreceiver, comprising a photodiode and a travelling-wave amplifier, monolithically integrated on a single InP chip, are characterized in OOK system experiments. Error-free performance below the FEC limit is achieved in back-to-back measurements up to 112 Gb/s.
The discrete Fourier Transform (DFT) or its more popular efficient algorithm, the Fast Fourier Transform (FFT) is one of the important mathematical functions in the toolbox of signal processing. To this date its processing speed is limited by the underlying electronic processors. We show that FFT signal processing limitations can be overcome by performing the FFT in the optical domain and demonstrate...
An optical FFT scheme is implemented and tested at 392 Gbit/s. It enables OFDM signal processing way beyond the bandwidth limits of electronics. The scheme operates with little energy as it exploits passive optical components.
Quasi-TM-mode propagation loss of 1.83 dB/cm at lambda = 1.565 mum is achieved in horizontal Si(amorphous)-SiO2-Si(crystalline) slot waveguides with 8.3 nm slots fabricated on silicon-on-insulator. Waveguide loss is measured using a ring resonator with Q ~ 3x105.
This paper presents an integrated photonic MEMS switching system. The switching system consist of two perpendicular photonic crystal (PC) surface waveguide joined together to form a waveguide bend. An elliptical micro-mirror driven by a comb drive actuator is positioned with its foci at the end cells of the waveguide bend to provide the switching mechanism. When the position of the mirror is displaced,...
