The helium–neon (HeNe) laser used to be a staple in every industrial or university lab having anything to do with photonics, as well as in numerous commercial products such as barcode scanners. They are now less common but still essential for many

Composite-cavity electro-optic microchip lasers have been proposed as a source for high-speed, low-noise microwave and optical signals. Such signals can be produced from a single short-cavity laser using the coupled optoelectronic oscillation archite

Future communication systems will require high data rates and flexible modulation. Direct optical phase modulation of two microchip lasers by information-bearing signals allows for high-rate delivery via fiber to a basestation. At the basestation, th

This paper reports on the optical generation of a rapidly tunable millimeter-wave subcarrier for lidar-radar. The millimeter-wave signal is generated by beating the output from two Nd:YVO/sub 4//MgO:LiNbO/sub 3/ electrooptical monomode microchip lase

The hazards of large high power lasers are well recognized, and the necessity for controlling these hazards justifiably enjoys wide consensus. However, physically small lasers, or those with relatively low output power (e.g. Class 3B), can also prese

The Integrated Tactile Network Architecture or ITNA is a hierarchical system for managing the interaction of tactile sensing and motor control in the 3-D active sensory environment. The overall ITNA includes custom dedicated hybrid front end tactile

A distributed testbed designed to support the development of a multi-sensory (vision and tactile) system for investigations in "active perception" of three dimensional objects is presented. Active perception means being able to not only see and feel

A scheme for QAM modulation of fiber radio signals is presented using direct vector modulation of electro-optically tunable solid state microchip lasers and photonic down-conversion. Advantages of this approach include high speed, small size, low cos

Compact solid-state lasers are an attractive potential source for high speed, low noise optical pulses suitable for microwave photonic systems such as optical A/D conversion or digital communications. These small devices can be mode-locked at the fun

Phase modulated coherent fiberoptic links can potentially provide exceptionally high spurious free dynamic range (SFDR) and low noise figure (NF). Critical issue is the development of a strictly linear phase demodulator. In this paper we describe a p
