TE-TM mode converter

A TE-TM mode converter utilizes a Y-cut lithium niobate crystal (10) which includes a straight titanium-diffused channel (12) extending along the Z-axis of the crystal (10). A parallel pair of electrodes (14,16) lie symmetrically on opposite sides of the channel (12). A.c. and d.c. voltage supplies...

Beschreibung
Zusammenfassung:	A TE-TM mode converter utilizes a Y-cut lithium niobate crystal (10) which includes a straight titanium-diffused channel (12) extending along the Z-axis of the crystal (10). A parallel pair of electrodes (14,16) lie symmetrically on opposite sides of the channel (12). A.c. and d.c. voltage supplies (22,20) are connected to the electrodes (14,16) to supply voltages so as to effect complete conversion from one direction of polarization to the other direction of polarization of a wave applied as an input to one end of the channel (12) for abstraction at the opposite end.
