Title:
LIGHT SOURCE MODULE
Document Type and Number:
WIPO Patent Application WO/2021/149621
Kind Code:
A1
Abstract:
One embodiment of the present disclosure relates to a light source module that can dynamically control the phase distribution of light. The light source module comprises a semiconductor laminate part. The semiconductor laminate part includes a laminate constituted by an active layer and a photonic crystal layer that generates Γ point oscillation, and has a phase synchronization unit and an intensity modulation unit aligned along the Y direction, which is one of the resonance directions of the photonic crystal layer. The laminate constituting a portion of the intensity modulation unit has M pixels (M is an integer of 2 or greater) aligned along the X direction. Each of the M pixels includes N1 sub pixels (N1 is an integer of 2 or greater). The length defined along the X direction of an area comprising N2 continuous sub pixels (N2 is an integer of 2 or greater and N1 or less) among the N1 sub pixels is smaller than the light-emitting wavelength of the active layer. The light source module outputs laser light along the direction that intersects both the X direction and the Y direction from each of the M pixels included in the intensity modulation unit.
