Latest Patents
One of his latest patents is an improved optical circulator that efficiently transfers light from a first optical port to a second optical port, and from the second port to a third port. This circulator incorporates non-reciprocal polarization rotators, birefringent beam splitters, and combiners. Additionally, it features a polarization-dependent light bending device made up of two tapered birefringent plates. This innovative light bending device compensates for the angle between the first light beam emanating from the first port and the second light beam propagating to the third port. The design allows for the coupling of the first and third fibers to the light beams using a single lens.
Another patent by Guo also focuses on an improved optical circulator, which includes both reciprocal and non-reciprocal polarization rotators, birefringent beam splitters, and combiners. This version also features a birefringent walk-off element and a similar polarization-dependent light bending device. The advancements in this patent further enhance the efficiency of light transfer between optical ports.
