Lasing Dynamics of a Novel Silicon Photonic Crystal Cavity
نویسندگان
چکیده
In this paper we proposed novel silicon laser design based on the dispersion engineered photonic crystals. With the unique self-collimation property, we design an optical cavity with a Q factor of 2000. The strong mode confinement in the low index active material offers an opportunity to realize a lasing mechanism. To investigate the lasing dynamics we introduce the rate equations of atomic system into the electromagnetic polarization. With these auxiliary differential equations we solve the time evolutions of the electromagnetic waves and atomic populations by using the FDTD method. DOI: 10.2529/PIERS060907132027

Coupled-mode theory for stimulated Raman scattering in high-Q/V(m) silicon photonic band gap defect cavity lasers.
We demonstrate the dynamics of stimulated Raman scattering in designed high-Q/V(m) silicon photonic band gap nanocavities through the coupled-mode theory framework towards optically-pumped silicon lasing. The interplay of other chi((3)) effects such as two-photon absorption and optical Kerr, related free-carrier dynamics, thermal effects, as well as linear losses such as cavity radiation and li...

We report here an optically pumped hybrid III-V/Si photoic crystal surface emitting laser (PCSEL), consisting of a heterogeneously integrated III-V InGaAsP quantum well heterostructure gain medium, printed on a patterned defect-free Si photonic crystal (PC) bandedge cavity. Single mode lasing was achieved for a large area laser, with a side-mode suppression ratio of 28 dB, for lasing operation ...

Nano cavities based on silicon and indium phosphide materials have been comparedin this study, considering field intensity enhancement factor. The results of FDTD based simulations declare that the Si nano-cavity improves confined optical field about 7.7 times higher than the InP based nano-cavity. The introduced dielectric nano-cavities support resonance wavelength at about λ=1.55 μm.

We measure the lasing dynamics of single and coupled photonic crystal nanocavity array lasers fabricated in the indium gallium arsenide phosphide material system. Under short optical excitation, single cavity lasers produce pulses as fast as 11 ps full width at half maximum , while coupled cavity lasers show significantly longer lasing duration which is not explained by a simple rate equation m...
