EXTERNAL MODULATION
... • Slope efficiency of laser diodes is limited by fundamental quantum efficiency (100% max), whereas for external modulation the slope efficiency scales with CW laser power. • Laser diodes limited to 30 GHz max (unless optical injection locking is used), whereas up to at least 100 GHz has been report ...

The Fresnel Biprism
... some potential error in setting up the system in that the rib of the prism was meant to be at the centre of the illuminated area, this is fairly subjective as the area surrounding the rib was illuminated weakly and so it was difficult to determine where the centre of this area was. The alignment of ...

Monte-Carlo Simulation of Stellar Intensity Interferometry by Janvida Rou
... SII presents advantages: it is essentially insensitive to atmospheric turbulence, it does not require high quality optics, and it permits large baseline and short wavelength measurements without extra difficulties. However, since SII relies on a second order effect, it is a less sensitive technique ...
