Abstract :
A delay line of multimode Si-wire waveguide folded with 45deg mirror bends is described. A 17 cm waveguide with a core size of 1times3 mum2 was integrated in an area of 0.85 mm2. The waveguide generated a constant group delay of 2 ns in the entire C-band with a typical optical loss of 14 dB. It also exhibited an error-free operation for 10 Gbit/s optical data signals.
