Stabilization of self-mode-locked quantum dash lasers by symmetric dual-loop optical feedback
Haroon Asghar, Wei Wei, Pramod Kumar +2
We report experimental studies of the influence of symmetric dual-loop optical feedback on the RF linewidth and timing jitter of self-mode-locked two-section quantum dash lasers em…
Optimum stabilization of self-mode-locked quantum dash lasers using dual optical feedback with improved tolerance against phase delay mismatch
Haroon Asghar, Ehsan Sooudi, Pramod Kumar +2
We experimentally investigate the RF linewidth and timing jitter over a wide range of delay tuning in a self-mode-locked two-section quantum dash lasers emitting at ~ 1.55 micron a…
Unraveling the Phase-amplitude Coupling Modulation in a Delay-Coupled Diode Lasers Functionality
Pramod Kumar, Sudeshna Sinhac, Vishwa Pald +1
We numerically investigate the effect of phase-amplitude coupling modulation on power spectra in semiconductor lasers subject to optical injection in a face to face configuration,…
Unveiling spatial correlations in biophotonic architecture of transparent insect wings
Pramod Kumar, Danish Shamoon, Dhirendra P. Singh +2
We probe the natural complex structures in the transparent insect wings by a simple, non-invasive, real time optical technique using both monochromatic and broadband femtosecond la…
Sub-microscopic modulation of mechanical properties in transparent insect wings
Ashima Arora, Pramod Kumar, Jithin Bhagavathi +2
