Abstract

Photonic crystal nanolaser [1] is a tiny laser suitable for sensing applications [2]. It is simply fabricated by patterning and etching an epiwafer and operated by photo-pumping. Owing to a small device area of ~(10 µm)2, large-scale integration of many nanolasers is also straightforward. The nanolaser acts as a sensor because it changes its wavelength and emission intensity with the surrounding index and electric charges, respectively. Our main target is sensing bio-molecules toward medical diagnoses, sanitary supervision, etc. For detecting biomarker proteins, ELSA is widely used. However, it needs complicated procedures, resulting in a high cost. Moreover, the detectable concentration by standard ELISA is in the sub-pM regime, which is sometimes insufficient for reliable diagnoses from human blood. The nanolaser sensor has achieved a sensitivity and selectivity higher than ELISA’s.
