Background and Motivation Evolution in laser technology - The available bandwidth has increased. - Output wavelength can be tuned New shutter technology needed - System to block range of wavelengths. Infrared modulator -IR modulator less develop -High spec in open transmission

Background and Motivation Modular using oxide shutter - Vanadium oxide is implemented - Thermochromic property Open/Closed mode operations - Open mode transmittance is high - Closed mode reflectance occurs

The Design Deposit oxide on glass panel by sol-gel method Design a micro heater attached to glass Implement testing system for shutter characterization Add photodetector for display

Deliverables of the Design Project Produce optical shutter designed for 3-5um Characterize the shutter for optical performance and switching time. Evaluation of measurements would give guidelines development of the shutter in a real system. Laser protection should have % open transmission and less than 1 % (30 dB) closed transmission The switching time from open to closed mode in the order of µs-ms.

Design Alternative Implementing modular as real system Can be used as data storage Window coating application Military applications

MDR specifications Design microheater and accompanying circuitry Preliminary design of the oxide shutter Have prototype for testing system
