Abstract
Abstract
We describe fixed wavelength ‘Extended Distributed Bragg Reflector’ (E-DBR) lasers and ultra-wideband ‘Integrated Coherent Tunable Lasers’ (ICTLs) with ultra-low noise operation. Discrete E-DBR lasers provide 15 Hz Lorentzian linewidth, -165dBc/Hz RIN, and >100mW power, initial ICTLs providing record 110nm tuning range and <200Hz Lorentzian linewidth.
TuG2.2 - 8-W-PEAK SELF-PULSATING PHOTONIC-CRYSTAL SURFACE EMITTING LASER WITH RING-SHAPED SATURABLE ABSORBER
Abstract
Abstract
We develop a self-pulsating photonic-crystal surface-emitting laser with a ring-shaped saturable absorber inside the current injection region, and realize self-pulsation with a peak power of 8W, a pulse width of less than 100ps, and a beam divergence angle of 0.5°.
TuG2.3 - POWER-BANDWIDTH TRADE-OFFS OF 25 GBPS TRIPLE VCSEL ARRAYS
Abstract
Abstract
Compact groups of three electrically-parallel 980 nanometer oxide-confined vertical-single-cavity surface-emitting lasers via on-wafer testing exhibit record room temperature small-signal modulation bandwidths of 20 to 25 gigahertz and corresponding large optical output powers of 60 to 20 milliwatts, respectively, and back-to-back 25 gigabit-per-second error-free data transmission.
TuG2.4 - IN-PHASE MODULATION BANDWIDTH ENHANCEMENT IN COUPLED MICROCAVITY LASER ARRAYS
Abstract
Abstract
Bandwidth enhancement in phased laser arrays is explained using small-signal frequency-domain analysis on coupled mode rate equations. In-phase modulation of asymmetric arrays produces bandwidth enhancement in agreement with experimental measurements.
TuG2.5 - A MONOLITHIC ELECTRO-OPTIC INTERFEROMETRIC TUNABLE LASER WITH A 44-NM TUNING RANGE AND BELOW 700 KHZ LINEWIDTHS
Abstract
Abstract
A monolithic interferometric tunable laser with a tuning range of 44 nm and linewidth below 700 kHz across all channels is reported. The laser features an intra-cavity coupler consisting of three electro-optically tunable arms with distinct lengths for supermode selection.
