A high-gain cladded waveguide amplifier on erbium doped thin-film lithium niobate fabricated using photolithography assisted chemo-mechanical etching
Youting Liang, Junxia Zhou, Zhaoxiang Liu +9
Erbium doped integrated waveguide amplifier and laser prevail in power consumption, footprint, stability and scalability over the counterparts in bulk materials, underpinning the l…
On-chip multi-color microdisk laser on Yb3+-doped thin-film lithium niobate
Yuan Zhou, Zhe Wang, Zhiwei Fang +12
We demonstrate an on-chip Yb3+-doped lithium niobate (LN) microdisk laser. The intrinsic quality factors of the fabricated Yb3+-doped LN microdisk resonator are measured up to 3.79…
Coherent mode-combined ultra-narrow-linewidth single-mode micro-disk laser
Jintian Lin, Saeed Farajollahi, Zhiwei Fang +10
Integrated single-mode microlasers with ultra-narrow linewidths play a game-changing role in a broad spectrum of applications ranging from coherent communication and LIDAR to metro…
