All other rights are reserved.The optical feedback dynamics of two multimode InAs/GaAs quantum dot lasers emitting exclusively on sole ground or excited lasing states is investigated. The transition from long- to short-delay regimes is analyzed, while the boundaries associated to the birth of periodic and chaotic oscillations are unveiled to be a function of the external cavity length. The results show that depending on the initial lasing state, different routes to chaos are observed. These results are of importance for the development of isolator-free transmitters in short-reach networks

Applications of Knowledge-Enabled CRM

Knowledge Management (KM) is the process of managing organizational knowledge from creating business value that will focus on creating and delivering innovative products or services and managing relationships with existing key stakeholders in the context of Customer Relationship Management (CRM). The value of KM and CRM is well recognized by many leading companies. Application of Knowledge-enabled Customer Relationship Management (KCRM) is a great opportunity to increase the customer value and provides a way to systematically attract, acquire and retain the customers. This study has taken a beauty enterprise as an example and focused on its franchise stores to perform a field study. A strategic knowledge-enabled CRM framework is introduced in order to classify the subjects by customer-oriented perspective. From the responses of the surveyed beauty enterprise, it is demonstrated how the companies can develop their customer connection strategies based on their current and future positions in four dimensions of the value compass model. Moreover, this study presented a conceptual model of KCRM to see how KM can help CRM implementation
