Focused ion beam milling of microchannels in lithium niobate

We investigate two different cuts of lithium niobate, Y- and Z-cuts, and observe that the experimental material removal rate in the FIB for both Y-cut and Z-cut samples was 0.3 μm 3 /nC, roughly two times greater than the material removal rate previously reported in the literature but in good agreement with the value we obtain from stopping and range of ions in matter (SRIM) simulations. Further, we investigate .

Lithium Niobate (LiNbO3).uk

Lithium niobate is particularly effective for second harmonic generation of low power laser diodes in the 1.3 to 1.55 µm range. For infrared generation by diffe rence frequency mixing, the peak power lim it is considerably lower than for 1.064 µm, being about 40 MW/cm2.

Lithium Niobate MEMS Device by Picosecond Laser Machining

shows picosecond laser machining is a viable method to process lithium niobate. Waveguides in Z cut lithium niobate crystal were fabricated using Ti-indiffusion techniques. After the fabrication of waveguides in lithium niobate, a Si02 film with a thickness of 0.3J.tm was deposited as a buffer layer.

optical materials cutting and polishing

At first glance, there would seem to be little advantage to using lithium tantalate over lithium niobate in the z-cut mode. However, lithium tantalate has practically no piezo-electric activity and so its dc and ac response are identical. One consequence of the piezo-electric activity in lithium niobate is that at certain frequencies it may be possible to set up acoustic resonances in the device when driven in a .
