The high-frequency skin-depth approximation for ohmic loss calculations is not ¨alid if the conductor thickness decreases and approaches the skin depth. This is the situation in many monolithic ( ) microwa¨e integrated circuits MMICs . The two asymptotes of loss, at dc and at high frequency of the a

Figure 3 Inverse quality factor calculated using the FDTD program as a function of the device radius
optical model is able to analyze complex VCSEL structures, and to generate the eigenfrequencies, power spectra, spatial distribution, and quality factor of the cavity modes. The key issues for the design of single-mode VCSELs that are addressed by this analysis are the quality factors of individual modes which may be used to study transverse mode discrimination. Future plans include the analysis of the optical properties of various complex structures such as selectively oxidized VCSELs.
