Abstract

Summary form only given. Magnetic field sensors have been constructed from two pieces of polarizing optical fiber fusion spliced to a single piece of low birefringence optical fiber. This configuration was mounted on a quartz bar for good geometric stability. A 780-nm laser diode pigtailed with polarizing fiber is used as the optical source for the sensor and light at the output is detected with a standard silicon detector. This device has been tested as a magnetic field sensor by placing it within a solenoid.
