We present 1.55 μm BTJ Short-Cavity VCSELs with modulation bandwidths in excess of 17 GHz. As shown by impedance measurements and impedance modeling, this excellent performance can be attributed to an improved parasitic roll-off frequency of 23 GHz.
1.55-mum vertical-cavity surface-emitting lasers with reduced parasitics and superior modulation bandwidth in excess of 10-GHz at 85degC are realized. Bit-rates of 17-Gb/s are demonstrated at room temperature, and error-free 12.5-Gb/s is achieved up to 85degC.
We experimentally demonstrate for the first time 1.55 mum vertical-cavity surface-emitting laser (VCSEL) transmission over 6.5 km single mode fiber (SMF) at 20 Gb/s for optical access networks. Characterization of the device is also investigated.
We present a monolithically integrated, InP-based 2D long-wavelength VCSEL array with coupling near fields. These lasers, utilizing a buried tunnel junction for current confinement, show partly coherent emission at 1.55 mum wavelength.
InP-based, long-wavelength VCSELs utilizing a buried tunnel junction (BTJ), emitting at 1.55 mum with improved active region and reduced parasitics are demonstrated. A superior modulation-bandwidth >10 GHz is achieved up to 85degC. Potential bit-rates of 12.5 or even 17 Gb/s are feasible for cost-effective 100 G Ethernet solutions at metro-range.
VCSELs at 1.55-mum with reduced parasitics and improved active region provide superior modulation-bandwidths >10 GHz up to 85degC. These bandwidths enable potential bit-rates of 12.5 or even 17 Gb/s for cost-effective 100 G Ethernet solutions.
Adjustable chirp is achieved in injection-locked, 10-Gb/s directly modulated, multimode 1.55-mum VCSELs for the first time, leading to 90times increase in standard single-mode fiber transmission distance to 90 km.
An optically injection-locked 1.55 mum VCSEL is demonstrated for use as an isolator-free, low-cost, directly modulated upstream transmitter in a WDM-PON where the injection-locking light is supplied by a modulated downstream signal.
Two-dimensional arrays of 1.55 mum vertical-cavity surface-emitting lasers (VCSELs) with continuous wave output powers in the Watt regime at room temperature are presented. Device characteristics are presented in detail and discussed on a theoretical basis.
We demonstrate adjustable negative chirp from a directly-modulated, injection-locked 1.55-μm VCSEL by controlling the injection parameters. Chromatic dispersion tolerance is enhanced by greater than 10times at 10-Gb/s compared to that of a free-running VCSELs.
We demonstrate a record resonance frequency enhancement of 1.55-mum VCSELs from 10 GHz to 107 GHz under ultra-high optical injection locking. Detuning and injection-ratio dependence are characterized to show the broad applicability of the technique.
We present a monolithically integrated, individually addressable 2D VCSEL array. These lasers, based on InP, emit at 1.55 mum and provide, with 10 GHz modulation bandwidth at moderate biasing conditions, high-speed capabilities for optical interconnects.
Various 1.55 mum vertical-cavity surface-emitting lasers (VCSEL) and two-dimensional VCSEL arrays with output powers up to 100 mW are presented. In a detailed investigation we derive scaling rules for high-power arrays.
Slow and fast light are achieved using novel master-modulated injection-locked 1.55 mum VCSELs at room-temperature. We achieve a full RF phase change of 2pi at >10 GHz over a wide bandwidth ~8 GHz.
