Quantum Well Bias Mirror for Phase Modulation in a Ring Laser Gyroscope
M.A. Sanzari, United States Patent Number: 5,416,583
Date of Issue: May 16, 1995
A semiconductor quantum well mirror is designed using optical thin film design techniques. The filter design creates a highly reflective semiconductor mirror for laser light in the visible region of the electromagnetic spectrum. Applying an electric field to the quantum well structure results in a modulation of the reflected intensity.

Superconducting Dual Junction Gyroscope Apparatus
M.A. Sanzari, United States Patent Number: 5,487,304
Date of Issue: January 30, 1996
A superconducting ring with quantum tunneling junctions is used to cause quantum interference ofmatter waves.; The phase shift between the waves resulting from rotation of the ring is measured as a voltage change across the quantum-tunneling junctions.

Apparatus and Method for Measuring Optical Activity
M.A. Sanzari, United States Patent Number: 6,687,012
Date of Issue: February 3, 2004
Collinear laser beams of counter-rotating circular polarizations emanating from a modified Zeeman laser is used in an optical heterodyning technique to measure the optical activity of chiral molecules.

Method and Apparatus for Distinguishing Materials
M.A. Sanzari, United States Patent Number: 7,049,596
Date of Issue: May 23, 2006
An optical fiber is used to guide infrared laser radiation emanating from a quantum cascade laser to measure the absorption of organic molecules in soft tissue, bone and cancerous tissue. Reflection and absorption from the tissue is mediated through the use on an attenuating total reflection prism.
