A 4-channel multi-wavelength laser integrated on a silicon waveguide circuit is realized. Waveguide-coupled output powers of 2mW and a side mode suppression ratio of more than 45dB for all channels is realized.

We present results from a laboratory characterization of integrated photonic arrayed-waveguide grating chips, which are a modified version of commercial arrayed-waveguide grating multiplexors, for the purposes of creating an integrated photonic spectrograph. Using a robust probing setup we measure the peak total efficiency of the chips to be ~75%. We measure the spectral resolution full-width h...

Optical amplifiers are important elements of photonic integrated circuits. We present a hybrid silicon evanescent amplifier utilizing a wafer bonded structure of silicon waveguide and AlGaInAs quantum wells. A chip gain of 13 dB with a power penalty of 0.5 dB at 40 Gb/s data amplification is demonstrated. ©2006 Optical Society of America OCIS codes: (250.5980) Semiconductor optical amplifiers; ...

In photonic crystals, light propagation is forbidden in a certain wavelength range, the bandgap. In a two-dimensional crystal composed of parallel high-refractive index rods in a low-index background a line defect can be formed by removing a row of these rods, which can act as a waveguide for frequencies in the bandgap of the crystal. In order to get more insight into the main features of such ...

A silicon photonic waveguide system with mode-division and wavelength-division-multiplexing capabilities is demonstrated. Error-free (BER < 10−12) data transmission of 2 modal channels and 3wavelengths operating with aggregate bandwidth of 60-Gb/s is realized. This work motivates future bandwidth scalability of silicon photonic interconnects.

Theoretical and numerical analyses of waveguide branches in a photonic crystal are presented. Conditions for perfect transmission and zero reflection are discussed. Based upon these conditions, numerical simulations of electromagnetic-wave propagation in photonic crystals are performed to identify structures with near-complete transmission. © 2001 Optical Society of America OCIS codes: 130.1750...

Highly efficient transmission of 1.5-microm light in a two-dimensional (2D) photonic crystal slab waveguide is experimentally demonstrated. Light waves are shown to be guided along a triple-line defect formed within a 2D crystal and vertically by a strong index-guiding mechanism. At certain wavelength ranges, complete transmission is observed, suggesting lossless guiding along this photonic one...

We demonstrated a GHz bandwidth slow light photonic crystal waveguide based PIN Mach-Zehnder modulator with V ×L as low as 0.0464 V mm, which is the lowest figure of merit reported so far. Keywords-slow light; photonic crystal; Mach-Zehnder modulator
