    Životopis

    Dubravko I. Babić rođen je u Zagrebu u Hrvatskoj. Diplomirao je na Fakultetu elektrotehnike i računarstva Sveučilišta u Zagrebu 1982., a magistrirao je 1984. godine i doktorirao 1995. godine na Sveučilištu u Kaliforniji, Santa Barbara.

    Od 1982. do 1985. godine radio je magisterij na kapacitivnim metodama mjerenja diskontinuiteta u energetskim vrpcama na AlGaAs/GaAs heterospojevima sa prof. dr. sc. Herbertom Kroemerom na Kalifornijskom Sveučilištu u Santa Barbari.  Od 1985. do 1989. godine radio je u tvrtki Avantek, Inc. u Santa Clari na razvoju mikrovalnih dioda za preklapanje (microwave switching diodes) i ograničavanje (limiter diodes) na frekvencijama do 40 GHz, i na varaktorskim diodama za naponski kontrolirane oscilatore na 3 GHz.  

    Godine 1989. pridružio se grupi za ultrabrzu optoelektroniku na Sveučilištu u Kaliforniji, Santa Barbara sa profesorima John E. Bowers i Evelyn L. Hu kako bi kao doktorand radio na razvoju lasera s vertikalnom rezonantnom šupljinom (VCSEL) gdje je 1995. prvi na svijetu demonstrirao VCSEL na valnoj duljini od 1550nm i koji je radio u kontinuiranom režimu na sobnoj temperaturi. Nakon doktorata, od 1995. do 1999. godine radio je u Hewlett-Packard laboratorijama u Palo Altu u Kaliforniji kao član tehničkog osoblja na razvoju VCSEL dioda korištenjem wafer-bonding tehnologije.

    Godine 1999. osnovao je startup Alvesta Corporation (Sunnyvale, CA) koja je razvila i proizvodila 10Gb/s višekanalne svjetlovodne module. Prvo je radio kao glavni direktor (Chief Executive Officer), a kasnije, od 2001. godine, kao glavni tehnički direktor (Chief Technical Officer).  Za Alvestu je dobavio $20 milijuna rizičnog kapitala i njome upravljao do prve prodaje proizvoda 2000. godine (Alvestu je kupila Emcore Corporation 2002. godine). Između 2003. i 2008. godine radio je kao savjetnik za Clariphy Communications, Inc. (Irvine, SAD) i XLoom Communications, Ltd (Tel Aviv, Israel) na razvoju optičkih i elektroničkih  komponenti za velike brzine prijenosa.

    Od 2008. do 2013. godine vodio je razvoj radiofrekvencijskih i milimetarskih pojačala temeljenih na AlGaN/GaN tranzistorima sa efektom polja koji su izrađeni na sintetičkom dijamantu kao potpredsjednik za tehnologiju i suosnivač  startupa Group4 Labs, Inc. (Fremont, CA) gdje je rakođer razvio postupak za lasersko oblikovanje dijamantnih čipova i izgradio sustav za mjerenje pouzdanosti tranzistora, a njegov tim je 2009. godine prvi na svijetu demonstrirao kompletno pojačalo (u kučištu) na 10 GHz temeljeno na tehnologiji galijevog nitrida na dijamantu (Group4 Labs je kupila tvrtka Element Six 2013. godine).  

    Nakon Group4 Labs sudjelovao je u osnivanju u Eridan Communications, Inc. (eridan.io), startup tvrtke u Santa Clari, CA, koja razvija polarne modulatore za bežične komunikacije temeljene na galijevom nitridu (GaN). Od 2012. godine radi na Fakultetu elektrotehnike i računarstva Sveučilišta u Zagrebu u Laboratoriju za primjenjenu optiku Zavoda za komunikacijske i svemirske tehnologije, a 2022. godine izabran je za redovitog profesora.

    Prof. Babić je također radio kao sudski vještak za intelektualno vlasništvo u SAD (2003-2012) i Hrvatskoj (2017 i 2023). Od 2005. godine piše patentne prijave za razne klijente, a od 2012 za FER.

    Njegovi znanstveni interesi uključuju optoelektroničke i elektroničke komponente za velike brzine prijenosa informacija, poluvodičke komponente i optiku. Objavio je preko 140 publikacija u časopisima i na konferencijama, ima 36 odobrenih patenata i napisao je jedno poglavlje u knjizi (Web of Science h-index 27, a Google Scholar h-index je 37).

    Istraživačka grupa sa Sveučilišta Stanford u Kaliforniji (SAD) je 2021 godine objavila studiju o znanstvenoj citiranosti koja rangira oko 160 000 najcitiranijih svjetskih znanstvenika u svim disciplinama (https://doi.org/10.1371/journal.pbio.3000918). Studija je objavila listu najutjecajnijih znanstvenika za cjelokupnu znanstvenu karijeru: prof. dr. sc. Dubravko Babić je u top 2% znanstvenika u svijetu u području "Optoelectronics and Photonics".
