The distribution of carrier density in an active layer of a vertical-cavity surface-emitting laser (VCSEL) produces a refractive index distribution, affecting the transverse-mode behavior of the VCSEL causing high-order-mode lasing. To achieve high-power fundamental-mode operation, we investigated the reduction in this effect by elongating the cavity. Experimental data show that the high-order mode started lasing immediately above a threshold in a lambda-cavity VCSEL with an active area large than 10 µm in diameter. By introducing a long monolithic cavity, high-order-mode lasing was suppressed. Theoretical results clearly show that such high-order-mode suppression is achieved because the effect of carrier-induced index change in the active layer is reduced by elongating the cavity.

This article discusses the fundamentals of optical fiber transmission technology and its basic building blocks. It aims to explain the principal characteristics of optical fibers, such as chromatic dispersion, of optical‐fiber amplifiers, including the noise they generate, and of semiconductor lasers. Also included is a discussion of optical receivers and their sensitivities, of nonlinear phenomena in optical‐fibers, of solitons, and of various transmission network architectures such as passive optical networks (PONs).
