Tunable semiconductor lasers for telecommunications applications

Introduction Tunable lasers are becoming important elements in optical networks to reduce costs. They could be used particularly for systems monitoring : a reference signal is transmitted and detected on each wavelength, thus informing on transmission quality. Or inventory costs could be drastically reduced by using tunable lasers as sparing sources or even as standard sources, to avoid the obl...

Broadband semiconductor optical amplifiers and tunable semiconductor lasers

Nonidentical multiple quantum wells (MQWs) had been widely used for broadening the emission or gain bandwidth of semiconductor optical amplifiers (SOAs). However, the carrier distribution among the MQWs is not uniform, leading to nonuniform gain contributed from different QWs. Thus using nonidentical MQWs for broadband purpose is not intuitively straightforward. Several factors need to be caref...

Tunable Diode Lasers

At the recent Photonics West and Optical Fiber Conferences, companies presented many new products, ranging from mechanical products to instruments to complex laser systems. As a product engineer, there is nothing quite like the feeling of standing in the booth, talking to potential customers about the product You’ve designed or built. But the real success happens when customers buy the product ...
