Edge Emitting Laser Far Field Divergence
Diffraction-limited far-field half-angle of an edge-emitting laser assuming a Gaussian mode with measured 1/e² waist radius.
Description
Diffraction-limited far-field half-angle of an edge-emitting laser assuming a Gaussian mode with measured 1/e² waist radius.
Edge Emitting Laser Far Field Divergence is a focused tool for the following task. Diffraction-limited far-field half-angle of an edge-emitting laser assuming a Gaussian mode with measured 1/e² waist radius. It reports Half Angle Radians from the values you provide rather than inventing measurements, coefficients, or professional judgment that are not part of the input.
When to use Edge Emitting Laser Far Field Divergence
Use this semiconductor calculation for first-order device, material, fabrication, interconnect, packaging, or reliability estimates when every coefficient and unit convention is known.
- Wavelength Meters (m)
- Required number in m.
- Waist Radius Meters (m)
- Required number in m.

How Edge Emitting Laser Far Field Divergence works
Diffraction-limited far-field half-angle of an edge-emitting laser assuming a Gaussian mode with measured 1/e² waist radius. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.
- Half Angle Radians (rad)
- Returned number in rad.
Limitations and assumptions
- Material composition, geometry, process history, temperature, electric field, bias, interfaces, parasitics, and fitted parameter ranges can invalidate a compact semiconductor model.
- Wavelength Meters must be at least 0.
- Waist Radius Meters must be at least 0.
- Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.
Alternative or Complementary approaches
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.

- Avalanche Breakdown Voltage Calculator
Estimate one-sided abrupt-junction avalanche breakdown voltage from the peak critical field and depletion width: Vb ≈ Ecrit·W/2. The factor 50 converts MV/cm·µm to volts and includes the triangular-field factor of one half. The estimate neglects curvature, edge termination, and the full ionization integral.
- Dislocation Density from Etch Pits
Convert a counted number of etch pits on a measured field area into a dislocation density per square centimeter. Formula: D [1/cm²] = N / (A [µm²]·1e-8), where 1 µm² = 1e-8 cm², N is integer pit count ≥0, A>0 µm². Output D≥0 1/cm²; D=0 when N=0. Assumes each pit corresponds to one threading dislocation, uniform distribution, and accurate field area measurement.

Bisection searches N in [1e12, 1e21] cm⁻³ for 200 iterations (geometric mid). Inputs: carrierType 'n' or 'p', ρ>0 Ω·cm. Output: N>0 cm⁻³. Assumes 300 K, complete ionization, and low-field mobility.
