This paper presents a novel five level polibinary signaling modulation and experimentally demonstrates 10 Gbit/s generation and transmission up to 20 Km utilizing only 1.8GHz bandwidth. OCIS codes: (060.4510) Optical Communications; (060.4080) Modulation.

With an increasing demand on multimedia services, a design of high-speed data networks is an important task in the wireless mobile environment. EDGE (Enhanced Data rates for Global Evolution) is the next step in the evolution of GSM and IS-136 offering high data rate capabilities in the existing GSM spectrum [1] [2]. With the introduction of EDGE in GSM phase 2+ existing services like GPRS (bas...

We \vill present research associated }vith the sound modeling soft$~rare called Lemur. In Lemur, Jve have developed a ne}v extension LOthe sinusoidal modeling technique of McAulay and Qua~ieri to accommodate sounds having significant non-sinusoidal energy. Lemur models sounds as a collection of par[ials having amplitude, frequency, and band!vidth envelopes. Band!vidth envelopes allotv Lemur [o ...

We present a system for sound modeling and synthesis that preserves the elegance and malleability of a sinusoidal model, while accommodating sounds with noisy (non-sinusoidal) components. We use an enhanced McAulay-Quatieri (MQ) style analysis that extracts bandwidth information in addition to the sinusoidal parameters for each partial. To produce noisy components, we synthesize with sine wave ...

Optical modulators for optical interconnects require a small size, small voltage, high speed and wide working spectrum. For this purpose, we developed Si slow-light Mach-Zehnder modulators via a 180 nm complementary metal-oxide-semiconductor process. We employed 200 μm lattice-shifted photonic crystal waveguides with interleaved p-n junctions as phase shifters. The group index spectrum of slow ...
