Method for operating a frequency agile tunable self-injection locking laser system and self-injection locking laser system

Tobias Kippenberg, Anat Siddharth, Grigorii Likhachev

The invention relates to a Method for operating a frequency agile tunable self-injection locking laser system being formed by a laser device coupled to at least one optical resonator, wherein a diode current of a laser diode of the laser device is controll ...

Soliton Generation in a Gallium Phosphide Photonic-Crystal Fabry-Perot Microresonator

Tobias Kippenberg, Nikolai Kuznetsov, Alisa Davydova, Alberto Nardi, Miles Henry Anderson

Ring resonators have proven to be extremely successful for generation of temporal dissipative Kerr solitons, but their dispersion engineering is limited. We present a photonic-crystal Fabry-Perot resonator with record-high quality factors in gallium phosph ...

Generation of Optical Frequency Combs in an Optical Microresonator Pumped by a 780-nm Laser Diode in Self-Injection Locking Regime

Andrey Voloshin

Experimental data for the generation of optical frequency combs in magnesium fluoride microcavities with whispering gallery modes at 780 nm are presented. This wavelength corresponds to the normal group velocity dispersion for pumping by a laser diode oper ...

Laser-induced forward transfer of functional SU-8 microparts

Giovanni Boero, Zhiwei Yang

We have developed a robust and universal method to transfer functionalized SU-8 microparts with metallic patterns by laser-induced forward transfer (LIFT) technique. To overcome the difficulty of metal patterning on high-aspect ratio SU-8 microparts on the ...
