Title:
LIGHT DEFLECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/107614
Kind Code:
A1
Abstract:
In a light deflection device 100, a first VCSEL structure 110 is configured to receive coherent incident light 2 at an incident end, perform slow light propagation in a horizontal first direction while performing multiple reflection of the incident light 2 in a vertical direction, and extract emitted light 6 from an emission port 122 in the upper surface thereof. A DOE 130 is provided on the upper side of the first VCSEL structure 110. The DOE 130 diffracts the emitted light 6 of the first VCSEL structure 110 in the first direction.
