In this chapter we outline major principles of vertical-cavity surface-emitting laser (VCSEL)
design and operation. Basic device properties and generally applicable cavity design rules …

Recent developments in spatially multiplexed optical communication systems demand a
deeper understanding of mode coupling effects in fibers. Spatial multiplexing is being …

We investigated the gamma radiation response of fiber Bragg gratings (FBGs) inscribed in a
few-mode polymer optical fiber. The fiber had a graded-index CYTOP core of 20 µm and …

We developed a consumer-friendly interface graded-index plastic optical fiber (GI POF)
cable with the ballpoint-pen interconnects for uncompressed 4K/8K video transmission of …

A new method is proposed for investigating the bandwidth in multimode graded-index
plastic optical fibers (GI POFs). By numerically solving the time-dependent power flow …

We investigate 40-Gb/s cost-efficient transmitter for access and metro networks. This 40-Gb/s
transmitter comprises a standard directly modulated distributed-feedback (DFB) laser and a …

Internet traffic continues to grow with the increase of network-connected smartphones,
tablets, televisions, and monitoring devices in the Internet-of-Things (IoT) era. This trend will …

A simple method is proposed for determining the mode coupling coefficient D in graded
index multimode optical fibers. It only requires observation of the output modal power …

Intrinsic mode coupling in a graded-index plastic optical fiber (GI POF) is investigated using
the developed coupled power theory for a GI POF with a microscopic heterogeneous core …

We experimentally demonstrate that a graded-index plastic optical fiber (GI POF) can
significantly reduce reflection noise in a multimode fiber link with a vertical-cavity surface …
