Abstract
En 中文
As quantum technology advances; integrated optical chips demonstrate extensive potential in quantum information processing; atomic system measurements; and precision sensing. This paper introduces a design for a highly integrated; robust; and easily fabricated multifunctional silicon nitride (SiN) array microring chip emitter for optically pumped atomic systems. The chip emits uniformly distributed circularly polarized light at 795 nm and vortex light at 778.1 nm (l = 3) with vertical radiation. Experimental results align closely with theoretical calculations. This device is anticipated to simultaneously achieve optical pumping of polarized atoms and laser frequency stabilization in atomic systems; offering a significant direction for developing chip-scale optical emitters in quantum applications. It holds the potential to play a crucial role in atomic clocks; quantum communication; and quantum sensing.
