SKU: HVED
The HVED Series Analog High Voltage Drivers provides up to ±200 V with 1 MHz bandwidth or ±400 V with 0.5 MHz bandwidth, ideal for driving non-resonant EO phase modulators to modulate optical signals at wavelengths up to 1060 nm. A polarity alternation feature minimizes charge buildup from photorefractive effects, particularly at shorter wavelengths and higher power.
The drivers include an adjustable DC bias up to 50 V for precise performance tuning. For example, with a sweep range of -200 V to +200 V and a 10 V DC bias, the output shifts to -190 V to +200 V (clipping the positive side), while a range of -100 V to +100 V adjusts to -90 V to +110 V. This bias flexibility allows precise control, optimizing electro-optic device functionality.
For amplitude modulation, polarized light is essential because the modulation process relies on controlling the intensity of light based on its polarization state. By incorporating input and output polarizers, the extinction ratio (ER) of the device is significantly improved.
