Detectors: Options for Low-Light Applications
SLAWOMIR PIATEK AND EARL HERGERT, HAMAMATSU CORPORATION
Developed in the early 1990s, the silicon photomultiplier (SiPM) is a solid-state photodetector whose sensitivity to light rivals that of a photomultiplier tube (PMT) in a regime where a few hundred...
Selecting a Photodetector: Using WITS$ as a Rough Guide
Earl Hergert and Slawomir Piatek, Hamamatsu Corporation
Light is a versatile tool for investigating physical and chemical processes in nature. Any specific system being analyzed may, through the light it emits or reflects, communicate information about...
Powering Lasers: Evaluating Bench Power Supplies
Paul Corr and Patrick Klima, Arroyo Instruments LLC
A bench power supply should be thoroughly tested and characterized before it is used to power a laser. The quality of the controls and safety measures incorporated into a bench supply will need to be...
Detectors: Guideposts on the Road to Selection
Earl Hergert, Hamamatsu Corporation
Any number of medical, industrial, and analytical applications requires the detection of light. Chemiluminescence, bioluminescence, fluorescence, and atomic absorption are just a few, and all require...
Connectors and Splices: Correct Alignment Spells Success
Paula Trindell, Tyco Electronics
Just as an electronic connector provides a pluggable connection between electronic circuits, a fiber optic connector provides an optical one. The goal is joining a fiber to a transmitter, receiver or...
Photonics Packaging: Optical Communication Components
Torsten Wipiejewski, VNT Management Oy, German Office
Photonic components are key elements for the information technology (IT). Photonics technology covers the generation of information (cameras, sensors), its transportation (optical communication),...
Photonic Component Manufacturing: Moving Toward Automation
Bruce W. Hueners and Michael K. Formica, Palomar Technologies
Manufacturing the laser diode is complicated by the existence of multiple proprietary techniques and intellectual property barriers together with complex device physics and unique materials. ...
Semiconductor Lasers: An Overview of Commercial Devices
JDSU
Laser diodes vary widely in their wavelengths, powers, spectra and beam quality. Yet they share two fundamental components with all other lasers: an optical amplifier and a resonator that confines...
