    • Elimination of catastrophic optical mirror damage in continuous-wave high-power laser diodes using multi-section waveguides 

      Liu, Yuxian; Ebadi, Kaveh; Sünnetçioğlu, Ali Kaan; Gündoğdu, Sinan; Şengül, Serdar; Zhao, Yuliang; Lan, Yu; Zhao, Yongming; Yang, Guowen; Demir, Abdullah (Optica Publishing Group (formerly OSA), 2022-08-29)
      One of the persistent obstacles for high-power laser diodes (LDs) has been the catastrophic optical mirror damage (COMD), which limits the operating power level and lifetime of commercial high-power LDs. The output facet ...

    • Epitaxially-stacked high efficiency laser diodes near 905 nm 

      Zhao, Yuliang; Yang, Guowen; Zhao, Yongming; Tang, Song; Lan, Yu; Liu, Yuxian; Wang, Zhenfu; Demir, Abdullah (Institute of Electrical and Electronics Engineers Inc., 2022-12-01)
      We report on studying tunnel junctions and an optical cavity structure for developing epitaxially-stacked high-efficiency 905 nm high-power laser diodes. The GaAs tunnel junctions were explored via simulations and experiments ...

    • Multi-section waveguide method for facet temperature reduction and improved reliability of high-power laser diodes 

      Ebadi, Kaveh; Liu, Yuxian; Sünnetçioğlu, Ali Kaan; Gündoğdu, Sinan; Şengül, Serdar; Zhao, Yuliang; Lan, Yu; Yang, Guowen; Demir, Abdullah (SPIE, 2022-05-20)
      Catastrophic optical mirror damage (COMD) limits the output power and reliability of lasers diodes (LDs). Laser self heating together with facet absorption of output power cause the facet to reach a critical temperature ...
