Title:
MANUFACTURING METHOD FOR ADJUSTABLE OPTICAL PHASE ARRAY AND ADJUSTABLE OPTICAL PHASE ARRAY
Document Type and Number:
WIPO Patent Application WO/2021/056545
Kind Code:
A1
Abstract:
A manufacturing method for an adjustable optical phase array and the adjustable optical phase array. The adjustable optical phase array comprises: a substrate layer (10), a distributed Bragg reflector (20), a supporting layer (30), a piezoelectric layer (40), an antenna array (60), and a transducer module (50) used for performing mutual conversion on a phase control signal and a surface wave. The antenna array (60) and the distributed Bragg reflector (20) are used for forming a Fabry-Perot resonant cavity. A phase control signal outputted by a signal source is converted into the surface wave by means of the transducer module (50), and the surface wave is conducted into the antenna array (60) by means of the piezoelectric layer (40) so that the Fabry-Perot resonant cavity generates corresponding oscillation, an emergent phase of the antenna array (60) is adjusted, and a purpose of controlling a light beam is achieved.
