Fabrication And Characterization

We report on the fabrication and characterization of active waveguides in a TeO2-ZnO glass sample doped with Er3+/Yb3+ fabricated by direct laser writing with a femtosecond laser delivering 150 fs pulses at 1 kHz repetition rate. The waveguides exhibit an internal gain of 0.6 dB/cm at 1535 nm, thus demonstrating the feasibility of active photonics lightwave circuits and lossless components in such a glass composition.

Index Modulation

We report on micro-structuring of iron-doped lithium niobate using femtosecond direct laser writing (DLW) technique. Formation of extended, stable index modulation micro-structures, such as diffraction gratings and linear waveguides is achieved by translation of a focused femtosecond laser beam inside lithium niobate crystals. From diffraction efficiency of the recorded gratings refractive index modulation amplitude of n ~ 10-3 is estimated. It is demonstrated that the recorded structures can be optically erased and re-written.
