Title Epitaxy of advanced lasers 
Description To facilitate the use of transfer print methods for verticla cavity lasers in this project, we have made progress on the development of the epitaxy of advanced laser structures indluing the use of VCSELs on sacrifical layers and the use of novel distributed bragg reflectors to manage strain in very thick structures. This has been developed on a new MOVPE reactor installed in the national epitacy facility in Sheffield in 2022. The capability will eventually be made available to all UK researchers through the National Epitaxy Facility

Title Membrane fabrication methods for Vertical Cavity Semiconductor Lasers VCSELs) 
Description To facilitate the use of transfer print methods in this project, we have made progress on the development of separable membranes containing VCSEL devices. These devices will form a major part of this grant, but more generically the ability to transfer print operating VCSELs will be broadly applicable to other application areas. The capability will eventually be made available to all UK researchers through the National Epitaxy Facility

Description Creating an Innovation Pipeline for Compound Semiconductors in the UK 
Form Of Engagement Activity Participation in an activity, workshop or similar
Part Of Official Scheme? No
Geographic Reach National
Primary Audience Professional Practitioners
Results and Impact Under the auspices of the National Epitaxy Facility and supported by the Photonics Manufacturing Hub, a one day workshop on the infrastructure available to support innovation in compound semiconductors int he UK was held in February 2022. The meeting was online and attracted over 180 delegates from both academia, industry, government and research councils.
Outputs of the meeting are being actively fed into government consultations and will be followed up in summer 2022.
