The SLICE-DCC is a compact, efficient cw current controller for driving diode, interband, and quantum cascade lasers as well as semiconductor optical amplifiers and tapered amplifiers. Part of the Vescent SLICE series of high-performance, economical photonic control electronics, SLICE-DCC offers two channels of low-noise current control. Proprietary self-adjusting power supply technology auto- matically sets the compliance voltage to as high as 20 V – but no higher than necessary to drive your load – allowing you to drive a traditional diode or a quantum cascade laser with the same device and the same efficiency. The two channels operate independently – including the automatic compliance
