New imaging techniques could build new roadways in neural mapping and provide a better understanding of how the brain functions. A team at Columbia University, in conjunction with other institutions, is developing such imaging techniques as part of the federal BRAIN initiative. And they agree that photonics will ultimately play a key role in treating brain-related debilitating diseases and conditions.

WHITE PAPER
|
An Introduction to Pulsed-Current Laser Diode Drivers
IXYS Colorado
The paper helps the reader to understand pulsed-current laser diode drivers and choose the right one for his or her application by explaining the basics of how they work and the components that comprise them. Ideal and real current sources are defined and explained, leading to an explanation of compliance voltage. Datasheet specifications for real-world products are explained: Forward voltage drop Single-junction lasers vs. stacks Rise and fall times Three driver topographies are discussed: the voltage-controlled driver, the inductive-storage current driver, and the capacitive-storage current driver. Each is described in terms of circuit composition, advantages, disadvantages, limitations, and quality of pulse generation.

FEATURED VIDEO
DILAS – Fiber Coupled,
Multi-Single Emitter Module
Jorg Neukum, Director of Sales and Marketing at DILAS, talks about the Prism nominated Fiber-Coupled, Multi-Single Emitter Module. The compact size provides users with a manageable footprint for integrating the device into any OEM system. With fiber core diameters as small as 105µm for single diode laser bars and scalable power levels for multi-bar modules up to kilowatt level, the product line of fiber-coupled modules offers highest brightness and power at all wavelengths, for all applications.
