Abstract

The key factors in device performance for titanium diffused lithium niobate phase modulator are related to their fabrication parameters. Low optical loss, low drive voltage, and large bandwidth are considered the primary factors. The parameters involved in fabrication are the titanium strip width and thickness, diffusion time and temperature, electrode gap and length. Design examples with fabrication parameters tailored to meet performance needs of fiber gyroscope systems and amplitude modulators are highlighted. Results are given for completely fiber pigtailed packages. A new method for fiber pigtailing using precision ceramic ferrules is also reported.
