Modulation response of nanoLEDs and nanolasers exploiting Purcell enhanced spontaneous emission.
نویسندگان
چکیده
The modulation bandwidth of quantum well nanoLED and nanolaser devices is calculated from the laser rate equations using a detailed model for the Purcell enhanced spontaneous emission. It is found that the Purcell enhancement saturates when the cavity quality-factor is increased, which limits the maximum achievable spontaneous recombination rate. The modulation bandwidth is thereby limited to a few tens of GHz for realistic devices.

Modulation bandwidth of metal-clad semiconductor nanolasers with cavity-enhanced spontaneous emission
Analytical approximations for the direct-current modulation bandwidth are obtained which highlight the deleterious effect of enhanced modal refractive index on the resonance frequency of metal-clad nanolasers. The concomitant utilisation of Purcell cavity-enhanced spontaneous emission is shown, in principle, to compromise achievable modulation bandwidths further. Using simplified forms for the ...
متن کاملMetal-Cavity Nanolasers and NanoLEDs
We present the theory and experiment of metal-cavity nanolasers and nanoLEDs flip-chip bonded to silicon under electrical injection at room temperature. We first review the recent progress on microand nanolasers. We then present the design rule and our theoretical model. We show the experimental results of our metal-cavity surface-emitting microlasers and compare with our theoretical results sh...
متن کاملRoom temperature continuous wave operation and controlled spontaneous emission in ultrasmall photonic crystal nanolaser.
Photonic crystal slab enables us to form an ultrasmall laser cavity with a modal volume close to the diffraction limit of light. However, the thermal resistance of such nanolasers, as high as 10(6) K/W, has prevented continuous-wave operation at room temperature. The present paper reports on the first successful continuous-wave operation at room temperature for the smallest nanolaser reported t...

Static properties, relatively intensity noise and intensity modulation response in quantum cascade lasers (QCLs) studied theoretically in this paper. The present rate equations model consists of three equations for the electrons density in the conduction band and one equation for photons density in cavity length. Two equations were derived to calculate the noise and modulation response. Calcula...
متن کاملTransient chirp in high-speed photonic-crystal quantum-dot lasers with controlled spontaneous emission.
We report on a series of experiments on the dynamics of spontaneous emission controlled nanolasers. The laser cavity is a photonic-crystal slab cavity, embedding self-assembled quantum dots as gain material. The implementation of cavity electrodynamics effects increases the large signal modulation bandwidth significantly, with measured modulation speeds of the order of 10 GHz while keeping an e...
