Reliable Integrated Photonic Light Sources Using Curved Al2O3:Er3+ Distributed Feedback Lasers
IEEE Photonics Journal, 2017 We propose a curved erbium doped aluminum oxide (Al2O3:Er3+) distributed feedback (DFB) laser for a reliable integrated photonics light source. The curved structure allows us for compensation of the radially varying film thickness due to the Al2O3:
