Paper Abstract

Magnetically doped Fe:InP and Fe:InGaAsP was characterized for verdict coefficient. The verdet coefficient was measured to be 180°/mm/T for Fe:InGaAsP, which is higher than YIG. High mesa waveguide of Fe doped InP/InGaAsP was fabricated and characterized. Faraday rotation in InP/InGaAsP waveguide was measured for the first time. The measured verdict coefficient is 33.3°/mm/T, which is only four times smaller than that of YIG.
