Journal ArticleDOI
Mode-locked quantum-dot lasers
TL;DR: In this article, the authors describe how semiconductor quantum-dot structures can provide an efficient means of amplifying and generating ultrafast (of the order of 100 fs), high-power and low-noise optical pulses, with the potential to boost the repetition rate of the pulses to beyond 1 THz.
Journal ArticleDOI
High-power picosecond and femtosecond pulse generation from a two-section mode-locked quantum-dot laser
Edik U. Rafailov,Maria Ana Cataluna,W. Sibbett,N. D. Il’inskaya,Yu. M. Zadiranov,A. E. Zhukov,Victor M. Ustinov,D.A. Livshits,A. R. Kovsh,Nikolai N. Ledentsov +9 more
TL;DR: In this paper, a two-section quantum-dot laser that produces output powers up to 45 mW at 1260 nm was demonstrated. The pulse duration could be varied from 2 ps to as short as 400 fs at the 21 GHz pulse repetition rate.
Journal ArticleDOI
Ultrafast electroabsorption dynamics in an InAs quantum dot saturable absorber at 1.3μm
TL;DR: In this article, a direct measurement of the absorption dynamics in an InAs p-i-n ridge waveguide quantum dot modulator was performed under reverse bias conditions, showing a decrease of nearly two orders of magnitude.
Journal ArticleDOI
Fast quantum-dot saturable absorber for passive mode-locking of solid-State lasers
Edik U. Rafailov,S.J. White,Alexander A. Lagatsky,Alan Miller,Wilson Sibbett,D. A. Livshits,A. E. Zhukov,V. M. Ustinov +7 more
TL;DR: In this paper, stable mode-locking in a Yb : KYW laser by using a quantum-dot (QD) saturable absorber was demonstrated using a pump-probe technique to be /spl sim/1 ps.
Journal ArticleDOI
Enhancement of terahertz photoconductive antenna operation by optical nanoantennas
Sergey Lepeshov,Andrei Gorodetsky,Andrei Gorodetsky,Alex Krasnok,Alex Krasnok,Edik U. Rafailov,Pavel A. Belov +6 more
TL;DR: In this article, the main results of hybrid optical-to-terahertz antennas and photomixers are summarized and compared to their implementation, and further perspectives of their development including an application of all-dielectric nanoantennas instead of plasmonic ones.
