Optoelectronics Overview

Principles

Definition

Optoelectronics is the interdisciplinary field of study concerned with the development and application of electronic devices that interact with light, investigating the phenomena and principles at the intersection of optics and electronics. This field focuses on the design, fabrication, and characterization of components that emit, detect, or modulate light, bridging photonics and microelectronics for diverse technological applications.

Solid-State Foundations era

W. Streifer[1] was active at the Massachusetts Institute of Technology[3] and Stanford University[4] during the Solid-State Foundations era. His key contribution was the Distributed-feedback single heterojunction GaAs diode laser[7], which advanced coherent, stable light generation and feedback mechanisms essential for early optoelectronic devices. R. D. Burnham[2] had affiliations with the University of Toronto[5] and the University of Illinois Urbana-Champaign[6] during this era. His contributions, in the Distributed-feedback single heterojunction GaAs diode laser[7] study, helped cement the role of DFB architectures in enabling practical solid-state lasers and integrated photonic platforms.

Exciton and Hybrid Emitters era

Richard H. Friend [1] is associated with Weizmann Institute of Science [3] and Northwestern University [4] in this era. In his 1990 Light-emitting diodes based on conjugated polymers [7], he helped establish polymer LEDs as a viable, solution-processable platform, and his 1993 Efficient light-emitting diodes based on polymers with high electron affinities [8] further boosted brightness and efficiency, laying essential groundwork for tunable, hybrid emitters in this era. Donal D. C. Bradley [2] is associated with École Polytechnique Fédérale de Lausanne [5] and University of Cambridge [6] in this era. Bradley's contributions are embodied in Light-emitting diodes based on conjugated polymers [7] and Efficient light-emitting diodes based on polymers with high electron affinities [8], which together mark a major advance in polymer-based emitters and enabled device-level integration and spectral control central to this era.

Efficiency and Stability Engineering era

Richard H. Friend [1], affiliated with École Polytechnique Fédérale de Lausanne [3] and Radboud University Nijmegen [4], emerged as a central figure in this era of optoelectronics. His group pioneered Bright light-emitting diodes based on organometal halide perovskite [7] (2014) and Overcoming the electroluminescence efficiency limitations of perovskite light-emitting diodes [8] (2015), along with Highly Efficient Perovskite Nanocrystal Light‐Emitting Diodes Enabled by a Universal Crosslinking Method [9] (2016), advancing radiative yield and suppressing nonradiative loss for stable high-brightness devices. Aron Walsh [2], with ties to the University of Cambridge [5] and University College London [6], contributed a foundational CsPbX3 nanocrystal study—Nanocrystals of Cesium Lead Halide Perovskites (CsPbX3, X = Cl, Br, and I) [10]—that broadened bright emission and color tunability for solid-state optoelectronics. These results, exemplified by the 2015 Nanocrystals of CsPbX3 paper [10], supported the era’s push for nanomaterial engineering to boost radiative yield and device lifetime.
