Abstract

This study investigates the influence of controlled mechanical strain on the wavelength characteristics of Vertical- Cavity Surface-Emitting Lasers (VCSELs), crucial components in optoelectronics, particularly in data centers. Using a custom four-point bending module, we systematically analyze the impact of strain on VCSELs by examining the wavelength evolution under varying strain levels. we report a consistent blue shift in the laser’s wavelength with increasing strain while maintaining stable power output. These findings highlight the potential of strain manipulation as a reliable technique for wavelength tuning in VCSELs, offering prospects for enhancing their performance in optical communication applications.
