- ©2020 Optical Society of America.A defective Jones matrix is a 2×2 matrix that has only one polarization eigenstate, contrary to the more common case of diagonalizable matrices that have two eigenstates.We analyze the properties of a defective optical system and characterize the optical phase shift ¿ (dynamic and geometric) introduced by the system. Two scenarios are identified: (a) ¿ has a finite range, leading to the existence of two particular input states that experience minimum and maximum phase shifts. (b) ¿ spans the complete range from -¿ to ¿, leading to the existence of two input states whose output states are orthogonal. We solve the inverse problem of designing an optical system for both scenarios. Additionally, we determine the conditions to get physically realizable defective Jones matrices satisfying the passivity condition. Finally, we introduce a new defectivity parameter to characterize the degree of defectiveness of a Jones matrix.
