In this work we present the first steps towards achieving Photonic Crystals (PCs) operating in the Near-Infrared (NIR) wavelength range using Macroporous Silicon (MPS). The MPS structures herein shown are fabricated using Electrochemical Etching (EE) of silicon. Pores are arranged in a square lattice of 500 nm periodicity and pore size is around 200 nm to 350 nm. Preliminary results show straight...
In this study we compare the optical response of macroporous silicon photonic crystals with several cavities inside their structure respect to the obtained in the single cavity case. We show that there are as much raising peaks in the transmission spectrum as number of cavities are inserted in the middle of the structure. Even more, this study reports the enhancement in the peaks' features -e.g. base...
The effect of losses in photonic crystal structures on transmittance and reflectance has been studied by numerical techniques, and compared to fabricated macroporous silicon samples. Material absorption and tolerances of the pores play an essential role in determining performance in optical applications. The relevance of the structure geometry has been investigated through the porosity. The considered...
