Sanjay KrishnaInstructor: Sanjay Krishna, Professor

Research Area: Antimonide based narrow gap semiconductor materials, infrared detectors and focal plane arrays

Duration: Half-day

Date/Time: Friday, August 9 | 8:30 AM - 12:00 PM

Mid-infrared imaging (3-25m) has been an important technological tool for the past 60 years since the first report of photonic infrared detectors in the 1950s. There has been dramatic progress in the development of antimonide based detectors in the past decade with new materials like Type II strained layer superlattices (SLS) demonstrating very good performance. This tutorial will discuss the basics of infrared detectors, mention the phenomenology in the infrared that drive applications and recent advances in antimonide based infrared detectors.
