Waveplate Schematic and Operating Principles
Mathematical Foundations
Phase Retardation Calculations
Phase Retardation (δ):
δ = (2π/λ) × (nₒ – nₑ) × tWhere:
• λ = wavelength of incident light
• nₒ = ordinary refractive index
• nₑ = extraordinary refractive index
• t = crystal thickness
δ = (2π/λ) × (nₒ – nₑ) × tWhere:
• λ = wavelength of incident light
• nₒ = ordinary refractive index
• nₑ = extraordinary refractive index
• t = crystal thickness
Jones Matrix Representation
Quarter Wave Plate (λ/4):
J = e^(iδ/2) [cos²θ + ie^(-iδ)sin²θ (1-e^(-iδ))sinθcosθ]
[(1-e^(-iδ))sinθcosθ sin²θ + ie^(-iδ)cos²θ]Half Wave Plate (λ/2):
For δ = π: J = [cos2θ sin2θ]
[sin2θ -cos2θ]
J = e^(iδ/2) [cos²θ + ie^(-iδ)sin²θ (1-e^(-iδ))sinθcosθ]
[(1-e^(-iδ))sinθcosθ sin²θ + ie^(-iδ)cos²θ]Half Wave Plate (λ/2):
For δ = π: J = [cos2θ sin2θ]
[sin2θ -cos2θ]
Dual Wavelength Design
Dual Wavelength Optimization:
t = m₁λ₁/[2(nₒ₁ – nₑ₁)] = m₂λ₂/[2(nₒ₂ – nₑ₂)]Where m₁, m₂ are integer orders for wavelengths λ₁, λ₂
t = m₁λ₁/[2(nₒ₁ – nₑ₁)] = m₂λ₂/[2(nₒ₂ – nₑ₂)]Where m₁, m₂ are integer orders for wavelengths λ₁, λ₂
