Photonics Engineering Tools

Visualize the full electromagnetic spectrum in real time. Drag the slider to explore the inverse relationship between wavelength, frequency, and photon energy, from radio waves to gamma radiation.

Simulate how a Gaussian laser beam focuses through a lens. Adjust beam diameter and focal length to calculate spot size, divergence angle, and Rayleigh range across 5 optical element types.

Visualize light refraction in real time. Drag the incident ray to explore how light bends between two media such as air, water, glass and diamond and discover total internal reflection.

Visualize Gaussian beam propagation in real time. Adjust beam waist, wavelength, and M² to calculate divergence angle, Rayleigh range, and beam parameter product across near-field and far-field zones.

Model laser diode to fiber coupling in real time. Adjust fast and slow axis divergence, lens focal length, fiber NA and core diameter to calculate mode overlap, NA mismatch loss, and total coupling efficiency.

Calculate focused spot size, depth of focus, Rayleigh range, and peak intensity in real time. Adjust focal length, beam diameter, M², and input power with material damage threshold detection.
