## Abstract A novel variable optical attenuator (VOA) based on highβbirefringence (HiBi) fiberβloop mirror is proposed. The HiBi fiberβloop mirror is put into the temperatureβcontrolling box. As the temperature increases, the transmission spectrum shifts with nearly unaltered shape. The attenuation
