Using femtosecond laser with variable pulse duration we probe the limits of switching that exploits coherent absorption in nanostructured gold films. Switching contrast ratios of 7:1 with a modulation bandwidth exceeding 100 THz has been observed. All-optical signal processing is one of the rising f...
