Semiconductor lasers exhibit a rich array of dynamical behaviours when subject to optical feedback. Reflected light from an external cavity re-enters the gain region, altering carrier and photon ...

We investigate the mode-switching dynamics of an electrically driven bimodal quantum-dot micropillar laser when subject to delayed coherent optical feedback from a short external cavity. We ...

Regardless of its color, an LED's light output varies as a function of forward current and ambient temperature. As Figure 1 shows, an LED's light output can vary by as much as 150% over its ...

High-brightness LEDs are being touted as the next big revolution in lighting. They are already being used in applications such as architectural, theater, and automotive lighting and they are ...
