For TWDM-PON systems we report measurements of and mitigation methods for the unwanted wavelength drift of directly modulated burst-mode lasers due to self-heating of the laser junction.

The objective of this continuing investigation of indoor/outdoor/surface relationships has been to develop an accurate method for predicting and subsequently managing the accumulation rates and ult

With the recent development of double-clad Er-Yb fibers, signals in the 1550-nm band can be amplified to powers greater than 10 W, well above the range of conventional Er-doped fiber amplifiers (ED

Serial data link has been widely used in telecom industry.

Network latency and reliability are becoming critical performance indicators for future mission critical services based on wireless connectivity.

The introduction of chromatic dispersion compensation to lightwave systems provides an opportunity to measure properties of the compensation.

Measurement of radiated electric field emissions above 1 GHz is required in the United States by the FCC and Bellcore.

Gain-switched semiconductor laser pulses at 1.3 and 1.5micron were measured both with a high-speed InGaAs PIN photodiode and an IR synchroscan streak camera.

We demonstrate an electro-optic sampling system for the characterization of very-high-speed, long wavelength photodetectors.

It is well known that certain bands in the microwave region are attenuated considerably due to absorption by water vapour and oxygen in the atmosphere.
