Imperfect Competition

Para quien es de utilidad: •Alumnos de Tª Microeconómica IV, curso 3º LE. •Alumnos de las asignaturas de Tª de Juegos y Organización Industrial del Máster en Economía: Instrumentos del Análisis Económico. Estas notas sobre competencia imperfecta están dedicadas al estudio de estructuras de mercado caracterizadas por la existencia de poder de mercado. Se estudia en primer lugar el monopolio, dedicando una atención especial a los diferentes tipos de discriminación de precios. A continuación se presenta la Tª de juegos no cooperativos y se muestra su utilidad para analizar diferentes fenómenos económicos caracterizados por la interdependencia estratégica. Finalmente, se estudian diferentes modelos de competencia oligopolística y la estabilidad de los acuerdos colusivos.

The impact of imperfect symmetry on band edge modes of a two-dimensional photonic crystal with square lattice

A theoretical analysis has been performed by means of the plane-wave expansion method to examine the dispersion properties of photons at high symmetry points of an InP based two-dimensional photonic crystal with square lattice. The Q factors are compared qualitatively. The mechanism of surface-emitting is due to the photon manipulation by periodic dielectric materials in terms of Bragg diffraction. A surface-emitting photonic crystal resonator is designed based on the phenomenon of slow light. Photonic crystal slabs with different unit cells are utilized in the simulation. The results indicate that the change of the air holes can affect the polarization property of the modes. So we can find a way to improve the polarization by reducing the symmetry of the structure.

Analysis of mode characteristics for equilateral triangle semiconductor microlasers with imperfect boundaries

The influence of imperfect boundaries on the mode quality factor is investigated for equilateral-triangle-resonator (ETR) semiconductor microlasers by the finite difference time domain technique and the Pade approximation with Baker's algorithm. For 2-D ETR with a refractive index of 3.2 and side length of 5 mum, the confined modes can still have a quality factor of about 1000 as small triangles with side length of 1 mum are cut from the vertices of the ETR. For a deformed 5 mum ETR with round vertices and curve sides, the simulated mode quality factors are comparable to the measured results.
