Generally, the laser scribing was done after GaN-based light emitting diodes (LEDs) growth. This study verified that the utilization of laser scribing leads to an increase in the surface roughness of sapphire substrate sidewalls, which reduces the probability of total internal reflection from light striking the sapphire/air interface. Laser scribing also helps increase side light extraction intens... View full abstract»

Fiber optic Fabry-Perot sensors are commonly interrogated by spectral interferometric measurement of optical path difference (OPD). Spurious jumps in sensor output, previously attributed to noise, are often observed in OPD-based measurements. Through analysis and experimentation based on intrinsic Fabry-Perot interferometric (IFPI) sensors, we show that these discontinuities are actually caused by... View full abstract»
