The resulted optical transmitter device is motionless, polarization sensitive or insensitive, stable within the operational spectral region, and stable versus temperature. When an optical receiver is integrated, the transmitters become transceivers. The invention also includes the methods for manufacturing the wave guide beam steering device.
