Orbital Angular Momentum (OAM) Mode Control
The research delves into the intricate dynamics of OAM modes within multimode Vertical-Cavity Surface-Emitting Lasers (VCSELs). By precisely manipulating the injection current, distinct OAM mode components can be controlled, serving as independent information carriers. This forms the fundamental basis for encoding various holographic information channels.
The study highlights how current density spatial distributions in the active layer, influenced by effects like spatial hole burning (SHB), determine the gains of each OAM mode. This allows for injection current-dependent OAM modes, crucial for dynamic holographic control.
Hologram Design & Encoding
A novel current-addressed mode-multiplexed holography technique is introduced, integrating with multimode VCSELs. To overcome design complexities arising from unknown electrical fields, orthogonal OAM states are utilized to encode holographic images.
An enumeration algorithm is proposed to identify distinct OAM modes with dominant weighting coefficients, minimizing channel crosstalk. This enables the encoding of multiple holographic frames (e.g., from a windmill video or an MQR code) into different OAM orders, allowing for dynamic reconstruction.
Ultra-Compact VCSEL Chip Performance
The core innovation is the monolithic integration of laser-nanoprinted multiplexed holograms directly onto the VCSEL surface. This resolves the long-standing contradiction between dynamic light-field manipulation and system miniaturization.
Experimental validation demonstrates a 2x2 chip array (100x100 µm² unit area) achieving dynamic 3D display with an ultra-high refresh rate of ~1.93 GHz, making it the fastest and most compact chip-scale holographic system reported. The high-speed modulation capabilities of VCSELs are key to this performance.
Applications & Future Directions
This work establishes a versatile platform for numerous cutting-edge applications, including portable and wearable devices, ultra-high-speed short-reach interconnects, and advanced Virtual/Augmented Reality (VR/AR) systems, all benefiting from minimized latency.
Future exploration includes leveraging larger oxide apertures in VCSELs for even greater spatial mode support, integrating polarization-multiplexing strategies, and investigating chaotic-cavity VCSELs to further enhance holographic channel capacity and design complexity.
