Area of Science:

Nanotechnology

Background:

Polarizing beam splitters (PBS) are crucial optical components for manipulating light polarization.
Fused-silica gratings offer potential for high-performance optical devices.
Existing grating designs may have limitations in efficiency and performance.

Purpose of the Study:

To investigate a sinusoidal-shaped fused-silica grating as a highly efficient PBS.
To establish design guidelines based on grating structure and wavelength.
To compare the performance of sinusoidal gratings with rectangular gratings.

Main Methods:

Simplified modal method for initial analysis.
Rigorous coupled-wave analysis (RCWA) for grating profile optimization.
Design and simulation at a wavelength of 1310 nm under Littrow mounting.
Fabrication approximation using wet etching on a pre-manufactured rectangular grating.

Main Results:

A sinusoidal-groove PBS grating designed at 1310 nm achieved high efficiency (>95.98%) across the O-band (1260-1360 nm).
TM and TE polarized waves were diffracted into the zeroth and -1st orders, respectively.
Sinusoidal gratings demonstrated higher diffraction efficiency, extinction ratio, and lower reflection loss than rectangular gratings.

Conclusions:

Sinusoidal fused-silica gratings are highly effective PBS devices with excellent broadband performance.
The grating design parameters (groove depth/period ratio, wavelength/period ratio) are key for optimization.
The proposed sinusoidal grating design offers advantages over traditional rectangular gratings and can be approximately fabricated.
