High frequency electric signal sensor using an optical modulator

This work describes an experimental system for sensing and transmission of electric signals using optical coherence modulation of light. The system consists of a Ti:LiNbO3 optical coherence modulator acting as electric signal sensor. The main characteristics of coherence-modulated transmissions include the need of using broad-band optical sources and integrated optics lithium niobate electro-op...

High bit-rate combined FSK/IM modulated optical signal generation by using GCSR tunable laser sources.

We report on the generation of combined FSK/IM modulation format by using GCSR tunable laser sources. FSK modulation, up to 100 Mbit/s, has been achieved by modulating the phase section of a GCSR laser source. We experimentally demonstrate generation of combined FSK/IM modulation at 100Mbit/s and 10 Gbit/s, respectively. We also report on successful FSK label insertion using a SOA-MZI wavelengt...

Photonic Integrated Circuit for All-Optical Millimeter-Wave Signal Generation

Generation of millimeter-wave electronic signals and power is required for highfrequency communication links, RADAR, remote sensing and other applications. However, in the 30 to 300 GHz mm-wave regime, signal sources are bulky and inefficient. All-optical generation of mm-wave signals promises to improve efficiency to as much as 30 to 50 percent with output power as high as 100 mW. All of this ...

Microwave generation in an electro-absorption modulator integrated with a DFB laser subject to optical injection.

This paper presents a new technique to generate microwave signal using an electro-absorption modulator (EAM) integrated with a distributed feedback (DFB) laser subject to optical injection. Experiments show that the frequency of the generated microwave can be tuned by changing the wavelength of the external laser or adjusting the bias voltage of the EAM. The frequency response of the EAM is stu...
