An optical device includes non-reciprocal combination-device and a polarizer. The non-reciprocal combination-device has a principal direction and a reverse principal direction. The non-reciprocal combination-device includes a first birefringent wedge, a second birefringent wedge, and a non-reciprocal rotating element. The polarizer receives a first light signal from the second birefringent wedge traveling in the principal direction and transmits a second light signal to enter the second birefringent wedge in the reverse principal direction.
