High-bandwidth 1060nm VCSEL design with hybrid buried tunnel junction and oxide confinement

|

| Optica Verified
1060nm vertical-cavity surface-emitting lasers (VCSELs) offer low dispersion and transmission loss for optical interconnects, but conventional oxide-confined designs face challenges in thermal accumulation and parasitic effects. We propose a high-speed 1060nm VCSEL featuring a hybrid confinement structure that integrates a buried tunnel junction (BTJ) with an oxide aperture, along with an optimized 8nm BTJ position offset.
