1.5-mW single-mode operation of wafer-fused 1550-nm VCSELs
A. Syrbu,A. Mircea,Alexandru Mereuta,Andrei Caliman,C.-A. Berseth,Grigore Suruceanu,V. Iakovlev,M. Achtenhagen,Alok Rudra,Eli Kapon +9 more
TL;DR: In this paper, a 1.5/spl mu/m waveband wafer-fused InGaAlAs-InP-AlGaAs-GaAs vertical-cavity surface-emitting lasers (VCSELs) were demonstrated.
Journal ArticleDOI
High-performance single-mode VCSELs in the 1310-nm waveband
V. Iakovlev,Grigore Suruceanu,Andrei Caliman,Alexandru Mereuta,A. Mircea,C.-A. Berseth,A. Syrbu,Alok Rudra,Eli Kapon +8 more
TL;DR: In this paper, a 2-in wafer bonding process is optimized to produce very good on-wafer device parameter uniformity for VCSELs emitting in the 1310-nm waveband.
Journal ArticleDOI
Broadband MEMS-Tunable High-Index-Contrast Subwavelength Grating Long-Wavelength VCSEL
Il-Sug Chung,V. Iakovlev,Alexei Sirbu,Alexandru Mereuta,Andrei Caliman,Eli Kapon,Jesper Mørk +6 more
TL;DR: In this paper, a widely tunable single-mode 1.3 μm vertical-cavity surface-emitting laser structure incorporating a microelectromechanical system-tunable high-index-contrast subwavelength grating (HCG) mirror is suggested and numerically investigated.
Journal ArticleDOI
2.6 W optically-pumped semiconductor disk laser operating at 1.57-microm using wafer fusion.
Jussi Rautiainen,Jari Lyytikäinen,Alexei Sirbu,Alexandru Mereuta,Andrei Caliman,Eli Kapon,Oleg G. Okhotnikov +6 more
TL;DR: A wafer fused high power optically pumped semiconductor disk laser incorporating InP-based active medium fused to a GaAs/AlGaAs distributed Bragg reflector is reported, revealing the essential advantage of the wafer fusing technique over monolithically-grown all-InP- based structures.
Journal ArticleDOI
8 mW fundamental mode output of wafer-fused VCSELs emitting in the 1550-nm band
Andrei Caliman,Alexandru Mereuta,Grigore Suruceanu,Vladimir Iakovlev,Alexei Sirbu,Elyahou Kapon +5 more
TL;DR: A new record fundamental mode output power is achieved with wafer-fused VCSELs incorporating regrown tunnel junction and emitting at the 1550nm waveband.
