About This Webinar
Recent developments in on-chip spectrometers, driven by the increased efficiency of end applications enabled by on-chip components, have highlighted the need for compact, high-performance light sources. Significant advancements have been made in the integration of near-infrared (NIR) and mid-infrared (MIR) lasers on-chip, leveraging techniques such as heterogeneous integration (the use of various technologies and materials on the same platform) and semiconductor manufacturing.
However, existing designs often face challenges in balancing performance, size, and cost. Issues with thermal management, wavelength stability, and power consumption remain, limiting the widespread adoption of on-chip spectrometers. Despite these challenges, on-chip laser integration continues to hold promise for transforming applications into environmental monitoring, healthcare, and industrial process control. This presentation will examine ongoing work on on-chip integrated lasers with advanced features like NIR to MIR conversion to reduce the overall cost of integration.
