Metal Thin-Film Optical Polarizer  

Polatomic, Inc. 

Richardson, TX 
 

Method for making polarizing material by depositing ellipsoidal metal particles on a transparent surface

• Polarizing filter demonstrated with contrast of up to 10,000 at visible light wavelength
• Polarizering filters made for visible and near infrared spectral band (400 nm to 3000 nm)

• Received $600,000 contract with Lucent Technologies to apply to telecommunications products
• Spun off new firm, Integrated Photonics, Inc., with $5.5 million of investor funding to pursue thin film metal polarizers for telecommunication applications

• Replace crystal beam-splitter polarizers in science instruments which are expensive, bulky and of limited size
