Introduction Small Form Factor (SFF) optical transceiver packages for use at 1-2 Gbits/s data rates have been described by several authors [1-5]. These rely on dual miniature optical connectors such as the MT-RJ or the LC to provide optical-component case widths as small as one centimeter. Passive alignment of the optical fibers with the active optical devices is achieved with … [Read more...]
Application of Thermoelectric Coolers for Module Cooling Enhancement
Figure 1. Cooling power density for different T.E. cooler designs (adaped from Vandersande and Fleurial [6]). Introduction Many advances in computer technology have been made possible by increases in the packaging density of electronics. These advances began with the introduction of the transistor in 1947 and continue today with ultra-large scale integration at the chip level … [Read more...]
An introduction to thermoelectric coolers
Figure 1: Cross Section of a Typical TECouple Introduction Thermoelectric coolers are solid state heat pumps used in applications wheretemperature stabilization, temperature cycling, or cooling below ambient arerequired. There are many products using thermoelectric coolers, including CCDcameras (charge coupled device), laser diodes, microprocessors, blood analyzersand portable … [Read more...]
Thermoelectric thermal regulation systems
Thermoelectric temperature control systems are being used in an increasingnumber of applications. Typical applications of these systems are in thermalregulation of electronic enclosures, recirculating chillers for laser cooling,semiconductor process control and management of patient hypo- and hyperthermia. Thermoelectric coolers (TECs) are essentially solid state devices that … [Read more...]
