An apparatus, method and computer program product for emulating a persistent connection using http. 1 \u03bcm or longer, wherein the distributed Bragg reflector includes an alternate repetition of a low-refractive index layer and a high-refractive index layer, with a heterospike buffer layer having an intermediate refractive index interposed therebetween with a thickness in the range of 5-50 nm. An optoelectronic transceiver allows for data exchange with an electronic memory device housed in the adhesively sealed enclosure and allows for data exchange and for updating or modification of software code housed therein.
