Use this semiconductor calculation for first-order device, material, fabrication, interconnect, packaging, or reliability estimates when every coefficient and unit convention is known.

Transition Electron Volts (eV)

Required number in eV.

The cited overview of Quantum-cascade laser supplies background for the terminology and domain context used by this tool.^[1]

Photon wavelength of a quantum-cascade laser from intersubband transition energy in electronvolts. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.

Wavelength Micrometers (µm)

Returned number in µm.

• Material composition, geometry, process history, temperature, electric field, bias, interfaces, parasitics, and fitted parameter ranges can invalidate a compact semiconductor model.
• Transition Electron Volts must be at least 0.
• Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.

Compare the estimate with measured process data, current device documentation, and a higher-fidelity circuit, field, thermal, quantum, or TCAD model when the decision requires it.

• Laser Slope Efficiency Calculator

  Compute laser slope efficiency in watts per ampere from differential quantum efficiency and photon energy, where W/A numerically equals the efficiency fraction times photon energy in electronvolts.
