Phoenix Photonics, manufacturer of all-fibre optical components and modules, has introduced an inline power monitor to its product range. The noninvasive power monitor is a small-footprint device designed to replace a tap coupler—a photodiode with a single small-footprint package. The device is based on interaction with the evanescent field of the propagating signal and consequently is noninvasive to the optical path. It offers low insertion loss with high responsivity. Several standard models are available to accommodate power-range requirements in different applications. A single device will operate from 1280 to 1630 nm. The monitor is housed in a compact 10×5mm diameter package. Among other applications it is designed for EDFA gain modules, DWDM channel power balancing, power control, and optical-channel monitoring.

Polytec introduced the MMA-300, describing it as the world's first integrated laser Doppler vibrometry and stroboscopic video microscopy system for full-field 3-D characterization of MEMS dynamics. The MMA-300 combines the MSV-300 scanning laser vibrometer with the new PMA-300 planar motion analyser. It maps out-of-plane vibration while PMA-300 measures in-plane motion simultaneously. The analyser exploits the advantages of both techniques: the extreme accuracy, speed, and broad application of laser Doppler together with video microscopy's ability to measure in-plane motion of virtually any surface.

MSV-300 offers a measurement frequency range from near-DC to 30 MHz, including FFT and time domain processing. Whole-field vibration response is animated for specific frequencies or in the time domain. A laser vibrometer measures any vibration waveform in real time, including transient and random.

Applications include modal analysis, impulse response, settling times, resonant frequencies, Q-factors, calibration, FE model verification and reliability of MEMS, telecoms arrays, gyroscopes, and other "micromachines."

Limo is presenting its complete range of micro-optics for collimation, beam-shaping, and fibre-coupling for industrial high-power diode lasers at the forthcoming Laser 2003 Expo in Munich. The significant advantages of diode lasers can be widely deployed by using LIMO's optics in industrial applications. The collimation optics also benefit the beam-shaping of excimer lasers. Thus, LIMO is offering new homogenisation optics for lithography, material processing and medicine. LIMO's new M3 optics will be presented in Europe. They are already the basis for optical communications technologies for next generations of passive and active modulators, switches, and amplifiers.

For the first time, a "highest brightness" laser with 25 W at the output of a 100-µm fibre will be introduced. The offer of lasers with high power now also includes passively cooled lasers with output power up to 120 W.

Cypress Semiconductor has announced volume production of its field-programmable zero delay buffer (CY23FP12), a 200-MHz clock distribution device featuring a flexible architecture that can be customised to fit a wide range of applications. The single chip, which incorporates the functionality of an entire clock distribution portfolio, is implemented on Cypress's proprietary silicon oxide nitride oxide silicon (SONOS) technology and is fully programmable via manufacturing facility or desktop programmers. The buffer enables the user to define an application-specific clock distribution device with up to 12 outputs, customised input and output dividers, feedback topology (internal/external), output inversions for differential operation, and output drive strengths as well as a variety of other functional and performance characteristics. For additional flexibility, the user can mix and match multiple functions. This feature enables implementation of a number of distinct configurations, all of which are selectable via control bits on a single programmed device. Cypress's buffers also feature a proprietary circuit that shuts down the device in case of a reference clock source failure, thereby simplifying power-down schemes.
