Abstract:

We describe a sandwiched two-layer grating as a three-port beam splitter, which can achieve high-efficiency diffraction with polarization-independence in the 0-th and the ±1-st orders. Diffractive efficiencies of 32.4/32.9% can be diffracted into the 1-st and the 0-th orders for TE polarization. And 33.1/32.8% can be diffracted for TM polarization. Besides, good splitting ratio uniformity can be exhibited within the broad duty cycle for both TE and TM polarizations. Moreover, the positioning tolerance of the gratings that constitute the sandwich is analyzed.

Keywords:

a sandwiched two-layer grating, a three-port beam splitter, diffraction, polarization-independence, TE and TM polarizations
