A new resonance breaking in-fiber switch as an all-optical network component is investigated and presented. A transient grating is applied to break the transverse resonance of the fundamental waveguide mode and the power coupled into the higher order propagating mode is computed using coupled mode theory (CMT). The coupling of the modes with the grating forming beams in the evanescent region of the...
A novel femtosecond Yb-fiber based amplifier seeded with a cavity-dumped Yb:KYW laser oscillator is employed for the writing of waveguides. The presented results have been achieved with a pulse energy of 1.6 muJ at 420 fs and a repetition rate of 1 MHz. We created simultaneously written waveguide pairs in fused silica with separations varying from 175 mum to 6 mum, using a 20x microscope objective...
We have obtained optical pulses via hybrid modelocking in monolithic slab coupled optical waveguide lasers with average powers exceeding 220 mW at a wavelength of 1550 nm.
