Transfer printed multi-color integrated devices for visible light communication applications

Abstract

Integrated multi-color devices for visible light communication applications are fabricated by transfer printing blue-emitting GaN light emitting diodes (LEDs) onto a greenemitting LED array and a colloidal quantum dot color-converter structure.

“…This technique utilizes polymer stamps to controllably capture and release semiconductor devices and has been previously used for optoelectronic systems assembly. For instance, transferprinting protocols have been widely used to integrate micro-LEDs [10,11], III-V semiconductor components onto bespoke photonic platforms [12][13][14] and recently also to successfully transfer novel materials (e.g. MoS2 [15], graphene [16]).…”

“…This will in turn open great possibilities to assemble functional photonic devices using heterogeneous photonic components as building blocks allowing the development of photonic circuitry that could combine different material groups on a single photonic chip. For example, recent works have used transfer-printing protocols to integrate multiple-color microlight emitting diodes on a simple platform for next-generation visible light communications systems [10]. Besides that, this technique offers nearly 100 % transfer yields [17], thus building great confidence on its future adoption as a main manufacturing technique for next generation integrated optoelectronic systems.…”
