WebNov 1, 2024 · A resonant period gain structure is used in the InGaN/GaN multi-quantum well active region to enhance the coupling between the cavity mode field and the active layers. The optical field inside the cavity is modulated by the cavity length; thus, tunable lasing at different wavelengths is realized at different points of a single VCSEL chip. WebMar 27, 2024 · In addition, VCSEL can also improve the security of AR/VR retina display. When the VCSEL operates at high power, it can limit the output power of light, so in optical schemes such as retinal projection, the VCSEL can limit the brightness of the display screen to avoid light damage to the retina.
