High-temperature Operation of Membrane DR Lasers Integrated with Si Waveguide by Micro-transfer Printing Method
We fabricate a membrane distributed-reflector lasers with a Si waveguide by using micro-transfer printing, achieving a low threshold current of 1.1-3.7 mA in a temperature range of $25-80^{\circ}\mathrm{C}$ and good optical coupling between the laser output and 220-nm-thick Si waveguides.
