This circuit was designed to meet a medical application’s requirement to drive a laser diode with reasonable precision and a minimum of components and footprint (the device is now in clinical trials).

In low power laser diode modules the designer has the option to use the classical discrete solution or take advantage of fully integrated driver ICs. Often the component cost is the only driving ...

External TVS diodes can be used to supplement the internal clamping diodes of ICs. Surge ability of silicon TVS diodes are related to size. External TVS diodes can be 10x larger than internal clamping ...

Hybrid device: the photonic integrated chip developed in this study. (Courtesy: G Likhachev, EPFL) A new type of ultrafast tuneable laser based on low-loss lithium niobate integrated photonics could ...
