Feb. 23, 2011Ultra-high Speed, All-optical Wavelength Converters Using Single SOA and SOI Photonic Integrated Circuits
We report a new family of ultra-fast all-optical wavelength converters. The device architecture employs a single SOA and filtering elements integrated in silicon-on-insulator substrates. These schemes enable high-integration density and low power consumption.

Nov. 1, 2010All-silicon photonic crystal photoconductor on silicon-on-insulator at telecom wavelength
We demonstrate an all-silicon photodetector working at telecom wavelength. The device is a simple metal-semiconductor-metal detector fabricated on silicon-on-insulator. A two-dimensional photonic crystal nanocavity (Q = 60,000) is used to increase the response that arises from the linear and two-photon absorption of silicon. The responsivity of the detector is about 20 mA/W and its bandwidth is larger than 1 GHz.

Oct. 18, 2010High bandwidth on-chip silicon photonic interleaver
We demonstrate a 120 GHz 3-dB bandwidth on-chip silicon photonic interleaver with a flat passband over a broad spectral range of 70 nm. The structure of the interleaver is based on an asymmetric Mach-Zehnder interferometer (MZI) with 3 ring resonators coupled to the arms of the MZI. The transmission spectra of this device depict a rapid roll-off on the band edges, where the 20-dB bandwidth is measured to be 142 GHz. This device is optimized for operation in the C-band with a channel crosstalk as low as 20 dB. The device also has full reconfiguration capability to compensate for fabrication imperfections.

Jun. 3, 2010Reducing Polarization Dependent Loss of Silicon-on-Insulator Fiber to Chip Grating Couplers
For many telecommunication applications, low Polarization Dependent Loss (PDL) operation is mandatory. On the silicon-on-insulator photonic wire platform this can be achieved using polarization diversity configurations. However, as we show here, when using two dimensional grating couplers for near vertical fiber input and output, the low PDL bandwidth is limited. We propose and demonstrate the use of a π phase shifter in one of the arms of the polarization diversity circuit to effectively reduce PDL (0:15 dB PDL is shown) and increase the low PDL bandwidth.
