摘要: A gallium and nitrogen containing laser diode device. The device has a substrate material comprising surface region. region is configured on either non-polar crystal orientation or semi-polar orientation. recessed formed within second of the material, being between first third to block plurality defects from migrating an epitaxially overlying substantially free active
