Abstract
This invention proposed a temperature and optical frequency sensor using two different optical resonators. The fiber with different thermal expansion factor and refractive index can be used to sense the temperature variation. The optical resonators with different cavity lengths can be used to detect the frequency deviation. Applying a laser, a microprocessor and two optical resonators with different thermal expansion factors and resonate lengths, we invent the device which can detect the temperature and frequency simultaneously. Furthermore, the device can provide tunable and highly stabilized light source for optical system application.
