Such a resonator can be realized with an open cavity consisting of two plane or curved mirrors, as represented in Figure 2.7 linear cavity). Details of the stability conditions for different types of open resonators can be found elsewhere (Siegman, 1986). Other more sophisticated configurations, such as those of ring cavity lasers (Demtroder, 2003) and microlasers (Kasap, 2001) are also used.

Another major application for microresonators is in development and fabrication of novel light sources such as resonant-cavity-enhanced light-emitting diodes (LEDs), low-threshold microlasers, and colour flat-panel displays. In wavelength-sized microresonator stmctures, semiconductor material luminescence can be either suppressed or enhanced, and they also enable narrowing of the spectral linewidth of the emitted light (Haroche, 1989 Yokoyama, 1992 Yamamoto, 1993 Krauss, 1999 Vahala, 2003).

Depending on the size of an incorporated dye, the angle of the transition dipole moment to the c axis lies between 0° for long molecules and 72° for smaller ones. Therefore, if a small molecule is inserted into the channels of zeolite L, part of the emission will be parallel to the c axis. Due to the flat and parallel ends of appropriately prepared zeolite crystals, one can envisage to arrange crystals between two mirrors or to add a reflecting layer on individual crystals. This might lead to a microlaser with a plane-parallel resonator. Apart from experimental difficulties, the realization of a dye-loaded zeolite L microlaser appears to be feasible. 

Researchers also have been investigating microlasers. These lasers range from 1 to 5 microns in diameter and are carved from a multilayered...
