A faculty member of Sanandaj Islamic Azad University could design a new optofluidic biolaser based upon the photonic crystal slab with selectively dye-infiltrated air holes for the first time.

According to an ISCA report, Dr. Mohammad HazhirMozaffari, faculty member of engineering department of Shahrekord University, explained that Optofluidic biolasers are recently being considered in bioanalytical applications due to their advantages over the conventional biosensing methods Exploiting a photonic crystal slab with selectively dye-infiltrated air holes.

He added that they propose a new optofluidic heterostructure biolaser, with a power conversion efficiency of 25% and the spectral linewidth of 0.24 nm. Simulations show that in addition to these satisfactory lasing characteristics, the proposed lab-on-a-chip biolaser is highly sensitive to the minute biological changes that may occur in its cavity and can detect a single virus with a radius as small as 13 nm.

The result of the research was published in Photonics and Nanostructures as an Invited Paper.
