Um laser DFB emissor de superfície integrado à lente e sua aplicação em subconjuntos ópticos monomodo (OSAs) de baixo custo são discutidos. Ao usar o LISEL, é demonstrado acoplamento óptico de alta eficiência com número reduzido de componentes ópticos e embalagem não hermética. Projetar a lente integrada dos LISELs torna possível obter acoplamento óptico de alinhamento passivo a um SMF sem a necessidade de uma lente adicional. Para o acoplamento SiP, o ângulo de emissão de luz do LISEL pode ser controlado pelo ângulo do espelho e pelo deslocamento da lente. Foi demonstrada a capacidade de uma baixa perda de acoplamento de 3.9 dB entre o LISEL e um acoplador de grade na plataforma SiP. O LISEL com estrutura livre de facetas, integrando espelho DBR, PD e estrutura de janela em sua faceta final, apresentou o mesmo desempenho de laser que o laser convencional com revestimento de facetas AR. Um teste de armazenamento (teste de panela de pressão saturada (PCT) de 200 horas a 138°C e 85% de umidade relativa) mostrou que as características do laser não se degradaram com alta umidade, demonstrando o potencial para aplicação de embalagens não herméticas. Nossos resultados indicam que o LISEL é uma das fontes de luz promissoras para a criação de OSAs com boa relação custo-benefício.

Abstract: A lens-integrated surface-emitting DFB laser and its application to low-cost single-mode optical sub-assemblies (OSAs) are discussed. By using the LISEL, high-efficient optical coupling with reduced number of optical components and non-hermetic packaging are demonstrated. Designing the integrated lens of LISELs makes it possible to achieve passive alignment optical coupling to an SMF without the need for an additional lens. For SiP coupling, the light-emission angle from the LISEL can be controlled by the mirror angle and by displacing the lens. The capability for a low coupling loss of 3.9 dB between the LISEL and a grating coupler on the SiP platform was demonstrated. The LISEL with facet-free structure, integrating DBR mirror, PD, and window structure on its end facet, showed the same lasing performance as the conventional laser with AR facet coating. A storage test (200-hour saturated pressure-cooker test (PCT) at 138°C and 85% RH.) showed that the lasing characteristics did not degrade with high-humidity, demonstrating the potential for applying non-hermetic packaging. Our results indicate that the LISEL is one of the promising light sources for creating cost-effective OSAs.
