The Electro‐Optic MZ Modulator 

• Electro‐optic effect: the applied 

electrical filed modifies the 

material refractive index. 

• The induced index variation 

modulates the phase of the 

optical wave. 

• Materials available: 

• Piezolectric/ferroelectric 

crystals: Lithium Niobate, 

Lithium Thantalate; 

• Semiconductors (GaAs, InP); 

• Electro‐optic optic polymers.

Summary

Summary of GR468 Tests 

• Vπ, insertion loss, extinction ratio, 

and bandwidth measured on all 

components pre and post test 

• HTOL monitored every 500 hours 

• Visual inspection for hermeticity 

completed after every test. 

• Samples size of 11 pieces used for 

critical tests 

• Smaller sample sizes run for mechanical 

tests due to cost
