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