✦ Synopsis

We studied a fiber-optic temperature sensor based on the interference between LP and LP modes of a circularly symmetric few mode fiber.

01 02

Theoretical analysis predicting the sensitivity of such a sensor is presented; the predictions are in excellent agreement with the experimentally measured value. A simple scheme for practical implementation of such a sensor is also suggested. The proposed sensor should be easier to implement than the existing two-mode fiber sensors using elliptical-core fibers.

## Abstract A novel variable optical attenuator (VOA) based on high‐birefringence (HiBi) fiber‐loop mirror is proposed. The HiBi fiber‐loop mirror is put into the temperature‐controlling box. As the temperature increases, the transmission spectrum shifts with nearly unaltered shape. The attenuation
