Surface emission semiconductor laser element

摘要: PROBLEM TO BE SOLVED: To provide a surface emission semiconductor laser element in which oscillation transverse mode can be controlled. SOLUTION: A layer structure of material, where an 4 is sandwiched between upper and lower reflector structures 5, 2, formed on substrate 1. An opening located above the 5 coated with layers, e.g. dielectric films 8, 8A, transparent for wavelength light to form outgoing window 6A. Oscillation controlled by varying plan view
